Question: SEOUL, SOUTH KOREA U.S. President Donald Trump's decision to withdraw from the Iran nuclear agreement is not expected to derail diplomatic momentum to reach a deal to end North Korea's nuclear weapons program, but it could complicate the negotiation process, analysts say.
Trump on Tuesday announced that the United States is ending its participation in the 2015 Joint Comprehensive Plan of Action (JCPOA) that lifted sanctions on Iran in exchange for Tehran limiting its nuclear program, and would re-impose U.S. economic sanctions on Iran. The agreement was negotiated by the administration of Trump's predecessor, President Barack Obama, and involved five other world powers; Great Britain, France, Germany, China and Russia.
Trump's National Security Adviser John Bolton said the U.S. decision to re-impose sanctions on Iran will set a higher standard for North Korea nuclear talks by sending, "a very clear signal that the United States will not accept inadequate deals."
The U.S. policy reversal on Iran should not seriously impede diplomatic progress underway with North Korea, said Victor Cha, a noted Korea scholar with the Center for Strategic and International Studies in Washington.
"In terms of how the North Koreans would take it, I don't think they'd take it one way or the other. I don't think they'd see it as negative or positive because they think they're different from anybody else anyway. They think they're a very special case," Cha said at a CSIS conference this week.
While the Iran deal limited that country's efforts to develop a nuclear bomb, North Korea already possesses 20 to 60 nuclear warheads, according assessments by the U.S. Central Intelligence Agency and the Defense Intelligence Agency, and between 40 to 100 nuclear development facilities, according a report from the RAND Corporation security research organization.
But apprehension over whether future U.S. presidents would uphold a nuclear deal reached by Trump could reinforce the North Korean demand for early concessions.
John Delury, a North Korea analyst with Yonsei University in Seoul, said on Twitter, "I don't think this is insurmountable but it adds yet another layer of difficulty."
In some ways Pyongyang may be reassured that a deal reached with the Trump administration would likely be supported by the next administration to follow.

Question: "Hon? You still awake?"
Quiet.
Jan pulled herself out of the bed and stood up, looking around the dark room for anything. She needed something, something that she could grab onto, and hold, hold until it hurt, hold until blood made racing red lines down her arms, until her hands were raw. She left the room and walked quietly into the now guest room that had been Rob's. Opening the closet, she found the teddy bear that Rob had once confided in and held it in her arms tight as she slumped down on the bed. A quiet sobbing rang through the house accompanied only by the chime of the grandfather clock in the living room every fifteen minutes. As Jan lay on the guest room bed she soon resorted to deep gasps, knowing that meager tears would never be forceful enough to express her worry to those that listened. "Just bring him home, bring him home, bring him home," she mumbled over and over, each time changing the tone slightly in a desperate attempt to make her pleading sound more real.
She could hear the occasional snore of her husband and she hated him for it. What kind of person could find sleep at a time like this? Why wasn't he awake worrying? Why wasn't he with her? Her thoughts became dark like blood, evil little monsters eating at her sanity. If her son was crazy and not just a drug addict she could see how easy it was to fall over the line. "Please God, please God, please God, please Rob, Please Rob, Please Rob, Please Rob." Soon, a sleep came but it was peppered with demons. And as the sliver of sun peeked through the window, she held her false self-control tight and said little.

Answer: Who did the guest room belong to?

Question: Defense Secretary Jim Mattis promised Thursday the Pentagon will "notify" Congress before any possible military action in Syria, where the U.S. is considering responding to a suspected chemical weapons attack.

"There will be notification to leadership, of course, prior to the attack," Mattis said in his testimony at the House Armed Services Committee. "We will report to Congress. We will keep open lines of communication."

But notably, Mattis did not indicate the Trump administration would seek congressional approval before the strike, which presumably would target the government of Syrian President Bashar al-Assad.
Trump says the U.S. will soon launch "nice and new and smart" missiles in response to last week's suspected poison gas attack, which left scores dead in a rebel-held area. Trump blames Assad for the attack.

A U.S. attack is likely to upset a small but growing number of U.S. lawmakers who demand President Donald Trump first ask Congress to authorize any hostilities, citing the War Powers Resolution of 1973, a federal law intended to check the president's ability to wage war.
U.S. presidents, both Republican and Democrat, have long argued they have legal authority to order airstrikes and other short-term military campaigns if those engagements fall short of the "hostilities" mentioned in the War Powers Resolution.

Additionally, U.S. presidents have cited a pair of authorizations by Congress following the Sept. 11, 2001 terror attacks as justification for the near-constant U.S. strikes on Islamic militants around the world.

The Trump administration has used those authorizations as justification for its current war in Syria. The U.S. has 2,000 troops in Syria, and helps lead an international coalition against Islamic State in Syria and neighboring Iraq.

The overwhelming majority of U.S. lawmakers have not publicly objected to the administration's legal rationale for those missions. But as Trump considers expanding the U.S. war to include attacks on Syrian government targets, some in Congress are speaking up.

Answer:
Who will keep open lines of communication at the House Armed Services Committee?
