WASHINGTON (CNN) -- President Bush on Tuesday announced a troop deployment shift for America's two wars, a move that reflects a more stable Iraq and an increasingly volatile Afghanistan. President Bush said Tuesday that he soon will start bringing some U.S. troops home from Iraq. Through early next year, about 8,000 American troops will leave Iraq and not be replaced. Some 4,500 other U.S. service members will go to Afghanistan. Bush also emphasized the U.S. intention to help Pakistan defeat insurgents who are using the country's tribal areas to stage attacks in Afghanistan. "Iraq, Afghanistan and parts of Pakistan pose unique challenges for our country," Bush said Tuesday in a speech at the National Defense University in Washington. "Yet they are all theaters in the same overall struggle." Bush said he is making the Iraqi troop withdrawal decision based on a recommendation from top military officers, including Gen. David Petraeus, the highest-ranking U.S. military officer in Iraq.  Watch Bush announce the troop reduction in Iraq » . "He and the Joint Chiefs of Staff have recommended that we move forward with additional force reductions," the president said, citing military and political strides in stabilizing the country and dramatically bringing down violence. Bush adopted the entire recommendation from Petraeus, a senior military official in Iraq told CNN. The source said five people saw the plan before it went to the president. Debate the Iraq issue! Join The Forum . In explaining progress in the war effort, Bush cited the "surge" offensive, winning the hearts and minds of Sunni tribes, Iraqi political reconciliation efforts, economic improvements, an improved Iraqi army leading the fight against Shiite and Sunni insurgents, and a return of hundreds of doctors who fled the fighting. "Over the next several months, we will bring home about 3,400 combat support forces -- including aviation personnel, explosive ordnance teams, combat and construction engineers, military police and logistical support forces," he said. "By November, we will bring home a Marine battalion that is now serving in Anbar province. And in February of 2009, another Army combat brigade will come home. "This amounts to about 8,000 additional American troops returning home without replacement. And if the progress in Iraq continues to hold, Gen. Petraeus and our military leaders believe additional reductions will be possible in the first half of 2009." At present, there are about 146,000 U.S. troops in Iraq. An adviser to Iraqi Prime Minister Nuri al-Maliki welcomed Bush's decision. "We look at this step as a positive step that there is stability in Iraq, there is a real improvement in the security situation in Iraq and there is a real improvement in the capability of the Iraqi security forces in protecting and keeping the security in Iraq," said Sadiq al-Rikabi, al-Maliki's political adviser. Democrats were less than enthusiastic about Bush's announcement. The plan "may seem to signal movement in the right direction," but it "defers troop reductions until the next administration," said Rep. Ike Skelton, D-Missouri, chairman of the House Armed Services Committee. "More significant troop reductions in Iraq are needed so that we can start to rebuild U.S. military readiness and provide the additional forces needed to finish the fight in Afghanistan." Skelton said Iraq "cannot continue to overshadow other critical U.S. security needs." "The effort in Afghanistan must move to the forefront and once again become our top priority," he said. Democratic presidential nominee Sen. Barack Obama praised Bush for announcing additional troops for Afghanistan and "moving in the direction of the policy that I have advocated for years." However, "we will continue to spend $10 billion a month in Iraq while the Iraqi government sits on a $79 billion surplus," Obama said. "In the absence of a timetable to remove our combat brigades, we will continue to give Iraq's leaders a blank check instead of pressing them to reconcile their differences," he said. Obama criticized the timing and scope of Bush's move. "His plan comes up short -- it is not enough troops, and not enough resources, with not enough urgency," the senator from Illinois said of Bush's call for more troops in Afghanistan. In his speech, Bush praised other members of the U.S.-led coalition, saying many of those nations will be able to end their deployments to Iraq this year. He said Australia has "withdrawn its battle group" and Polish troops are "set to redeploy shortly." The president said Iraq and the United States will work "toward the conclusion of a strategic framework agreement and a status of forces agreement," pacts that will spell out the terms of their relationship. "These agreements will serve as the foundation for America's continued security support to Iraq once the United Nations resolution authorizing the multinational forces there expires on December 31." Bush focused his remarks just as strongly on Afghanistan, where al Qaeda and Taliban militants have been making a comeback. "For all the good work we have done in that country, it is clear we must do even more," he said. "As we learned in Iraq, the best way to restore the confidence of the people is to restore basic security -- and that requires more troops." He said that a Marine battalion of around 1,000 will deploy to Afghanistan in November instead of Iraq and that an Army combat brigade of around 3,500 will go in January. Bush said the U.S. would make additional forces available in 2009 and called on allies to increase their force levels. Bush said stepped-up insurgent efforts in Afghanistan have necessitated the increase of U.S. troops from "less than 21,000 two years ago to nearly 31,000 today." He said these troop increases and those by allies, including Britain, France, Poland, Bulgaria, Romania, Australia, Germany, Denmark and the Czech Republic, have resulted in what he calls a "quiet surge" in Afghanistan. Bush described challenges in Afghanistan that don't exist in Iraq. "This is a vast country," he said. "Unlike Iraq, it has few natural resources and has an underdeveloped infrastructure. Its democratic institutions are fragile. And its enemies are some of the most hardened terrorists and extremists in the world." He said Americans will help develop Afghan security forces and are improving efforts on the civilian side, adding more personnel to deal with issues of diplomacy, development, the rural economy and the fight against the drug trade.

(CNN)If that car parked in Harvard Yard is a rockin', school officials may soon come a knockin', because hanky-panky between students and faculty at the elite university has officially been banned. Specifically, the school adopted a new policy this week that prohibits romantic relationships between undergraduates and professors. The previous policy only did so between professors and the students they taught. Harvard released a statement saying a specially appointed committee "determined that the existing language on relationships of unequal status did not explicitly reflect the faculty's expectations of what constituted an appropriate relationship between undergraduate students and faculty members ... therefore, the committee revised the policy to include a clear prohibition to better accord with these expectations." The action comes nearly a year after the U.S. Department of Education announced it was investigating 55 colleges and universities, including Harvard, for violations pertaining to Title IX, the federal law prohibiting sex discrimination on college campuses. Harvard responded at the time by saying it had appointed its first ever Title IX officer, and that the school's president "recently announced the creation of a university-wide task force -- composed of faculty, students and staff -- that will recommend how we can better prevent sexual misconduct at Harvard." The new policy is the result of "a formal process to review Harvard University's Title IX policy," the school said.

(CNN) -- Andrew Sable wasn't in the market for new wheels, but he says the federal "cash for clunkers" program helped him get an offer he couldn't refuse. "I'd have been foolish not to take it," said Andrew Sable, who got $9,000 for his 1993 Jeep Grand Cherokee. The gas-guzzling 1993 Jeep Grand Cherokee his college-student son drives went bad last weekend. Ordinarily Sable would have fixed it, even though the vehicle was worth perhaps $2,000 at best. But, aware of the program that started this month, Sable took a $4,500 federal credit this week to trade in the Jeep and buy a new, more fuel-efficient Chrysler PT Cruiser. And Chrysler, eager to sell vehicles, threw in its own $4,500 incentive. The $9,000 in savings knocked the price to $8,900 before taxes and fees. "I'll never get $9,000 for this old vehicle [any other way]. I'd have been foolish not to take it," the 43-year-old Sable, an insurance underwriter living in North Bellmore, New York, told CNN after filing a report with iReport.com. He'll drive the PT Cruiser and let the son drive his Nissan. iReport.com: Read Sable's account of the purchase . Under the $1 billion program, people will be given credits of $3,500 to $4,500 to replace gas guzzlers -- generally vehicles with a combined city/highway fuel economy of 18 miles per gallon or less -- with new vehicles that are more fuel efficient. The old vehicles are crushed or shredded.  Watch CNN's Gerri Willis explain the "cash for clunkers" program » . The exact credit offered through the program --- officially called the Consumer Assistance to Recycle and Save Act of 2009, or CARS -- depends on how many more miles per gallon the new vehicle gets. Fuel economy thresholds for new vehicles vary according to type. New cars must have a combined city/highway fuel economy of at least 22 mpg. New SUVs and small or medium pickup trucks or vans must get at least 18 mpg. New large vans and pickups must get at least 15 mpg. The government put Sable's old Jeep at 15 mpg. His new PT Cruiser, which the program classifies as an SUV, gets a combined 21 mpg. Part of the program's intent is to get vehicles with low fuel efficiency off the road. Caroline Radtke, a 31-year-old who wrote about her purchase on iReport.com, was happy to oblige. Radtke and her husband this month got a $4,500 CARS credit for trading in their 2000 Isuzu Trooper (15 mpg) to buy a new Volkswagen Jetta SportWagen, a diesel-powered car that the program lists as getting 33 mpg. After the credit, they paid just under $26,000. "What was going out of my [old] vehicle was bad for the planet, and you're putting so much financially into the stupid thing to fill it up because it runs out so fast," Radtke, a freelance graphic designer living in San Antonio, Texas, told CNN after filing her iReport. "After driving it for eight and a half years, I wanted something more productive financially and more friendly to the Earth." The couple would have bought a new car without CARS, but the credit probably allowed them to get a nicer car than they otherwise would have, Radtke said. If they had sold the Trooper themselves, they might have gotten $3,000 if they were lucky, she said. iReport.com: Radtke's purchase . The CARS program isn't for everyone. The credit won't go toward used-car purchases. Also, people looking to get rid of their under-18-mpg vehicle might find they can get about the same or more than a CARS credit by selling it. But the program worked just fine for iReporter Julie Callahan, a Salt Lake City, Utah, woman who was looking to replace her 1990 Chevy C1500 pickup truck, which had more than 350,000 miles and is rated at 15 mpg. She and her husband already had a newer vehicle, but she used the truck to go to work and for other in-town purposes. But lately it started having shifting problems, and it was occasionally slipping going uphill. Like Sable, Callahan, 39, got $4,500 this week to turn in the old vehicle and buy a new PT Cruiser. And, like Sable, she also received a separate $4,500 credit from Chrysler. She'll be paying about $10,000 for her new vehicle after taxes and fees. The $9,000 she saved with the credits from CARS and Chrysler isn't too shabby, considering she figures her old pickup was nearly worthless because it had so many miles. iReport.com: How Callahan got $9,000 for her truck . "Without the incentives, I probably wouldn't have purchased a brand new vehicle," Callahan, who runs a science outreach program at the University of Utah, told CNN after filing her iReport. Unless it is renewed, the program will end November 1 or when funds allotted by Congress run out, whichever happens first. Trade-ins must be less than 25 years old, and their titles must be free of any liens. Consumers can go to a Web site, cars.gov, to learn the program's rules.
