(CNN) -- More than 2,000 lives lost. A vast and unfolding humanitarian crisis. And the downing of a civilian airliner that shocked the world. It's hard to imagine -- but true -- that the raging conflict between Ukraine and Russia, or at least Ukraine and pro-Russian rebels, all started with a humble trade agreement. As tensions run high over a Russian aid convoy described by Western leaders as a provocative incursion, reports of direct Russian military activity inside Ukraine and Ukrainian fears of an outright invasion, it's time to look back on how we got here, and where things are headed: . How it started . While the roots of the crisis run quite deep, what's happening now began to unfold in earnest in the fall of 2013. That's when then-Ukrainian President Viktor Yanukovych scuttled a trade deal with the European Union that would have pulled the country, so recently a satellite of the Soviet Union, toward Europe in the latest twirl of a dance that has lasted centuries. Instead, Yanukovych jumped at Russian President Vladimir Putin's offer to buy $15 billion in debt from his cash-strapped government and cut the price of vital natural gas to the country. Yanukovych's decision set off protests in Ukraine's more Europe-leaning west calling for the government's ouster. Security forces responded harshly, beating protesters and firing live ammunition into demonstrations, resulting in several deaths. As clashes spread, so did international anger over the situation. By late February, Yanukovych had fled to Russia, the government had fallen and a new pro-Europe government had formed to replace it. That, in turn, set off pro-Russian demonstrations in Crimea, a semi-autonomous Ukrainian republic and the location of a major Russian navy base. After thousands of Russian troops filtered into the territory -- purportedly at the invitation of Ukraine's self-exiled president -- Ukraine's regional parliament called a referendum on secession, and before you could say "borscht," Crimea was part of Russia. And it's here that things turned even uglier. Pro-Russian fighters occupied government buildings in the country's east, demanding a referendum on independence. Before long, rebel forces -- believed to be supported by Russia -- had taken control of major cities in Ukraine's east. Fighting broke out between the rebel groups and Ukraine's military, fighting that continues today. In a major and likely inadvertent escalation in July, a suspected surface-to-air missile believed to have been operated by pro-Russian rebels shot down Malaysia Airlines Flight 17, killing all 298 people aboard and hardening Western opinion, particularly in Europe, against Russia. What's happening now . Ukraine's military has been on the offensive recently against the pro-Russian forces, but those successes seem to have slowed. Russian troops remain camped along the Ukrainian border, Western leaders say. And Ukrainian officials said Tuesday that they had detained 10 Russian soldiers in the Donetsk region of eastern Ukraine, further evidence, Kiev says, of direct Russian involvement in the conflict. Meanwhile, the United Nations has warned of a growing humanitarian crisis sure only to get worse unless something is done to stem the fighting. What's next . A full-scale invasion is unlikely. While Putin's approval rating among Russians is sky-high, recent polling shows the Russian people aren't wild about an out-and-out invasion of Ukraine, said Robert D. Kaplan, the chief geopolitical analyst for Stratfor. "He may be a dictator, but dictators care about public opinion as much as democrats," he said. But any talk of peace from Putin is likely a stalling tactic. Putin is buying time so that he can continue slipping arms and aid to help rebels recover from their recent losses, said Heather Conley, senior vice president of Europe and Eurasia at the Center for Strategic and International Studies. "His best option is to have a permanent frozen conflict," she said. Fall and winter will slow the fighting. Kaplan said the colder seasons in Ukraine mean mud and mud means a slower tempo for military operations. Just don't expect total silence, he says -- there will still be fighting. Moscow will try to squeeze Ukraine. Putin will slow the flow of crucial natural gas and goods into Ukraine, putting further pressure on Kiev's economy and war-fighting ability. "The Russians will try everything to weaken the regime in Kiev," Kaplan said. The West has some soul-searching to do. Sanctions applied by the United States and Europe against Russia have so far only played into Putin's playbook, enhancing the image of an aggrieved Russia trying to shake off its detractors, Conley said. Putin's strategy of assembling a larger Russian empire has significant ramifications for Estonia and Latvia, Conley said, raising questions about just what the West will do to stop Russia if Putin chooses to further extend his reach. And what will it take to end this? Ukraine is a linchpin of Putin's plans for Russia, whether it's reassembling a historical empire or shoring up the Russian economy, Conley says. So whatever happens must support that. Kaplan says Putin can't pull back without gaining assurances that Ukraine will never become part of NATO. Ukraine, he said, needs assurances about its sovereignty and energy security.

Washington (CNN) -- Attorney General Eric Holder says the Justice Department plans to expand a review of police tactics to update training, technology and other standards around the nation. The aim, in part, is to produce broad national recommendations to enhance officers' safety, help them deal with new threats and also boost the use of technology such as police car and body cameras. In the wake of complaints about police handling of protests in Ferguson, Missouri, critics likely will also push for new standards to address police crowd control tactics and the use of force. The protests followed the shooting death of unarmed teenager Michael Brown by a Ferguson police officer in August. Associations representing police officers and executives have supported the idea of a commission to review standards. Holder, who speaks to a gathering of police officers in Little Rock, Arkansas, on Wednesday, plans to announce his support for such a commission to do the most expansive review of police tactics in 50 years. Holder on Supreme Court's Ohio early voting decision: A 'step backward' Holder, in prepared remarks, said the goal of the ongoing review is to "swiftly confront emerging threats, better address persistent challenges, and thoroughly examine the latest tools and technologies to enhance the safety, and the effectiveness, of law enforcement." An ongoing review is already doing some of the work. But Holder says expanding it would "consider the profession in a comprehensive way and to provide strong, national direction on a scale not seen since President Lyndon Johnson's Commission on Law Enforcement nearly half a century ago." Excerpts of his speech were provided by the Justice Department before delivery. Holder's speech is also intended to mark the 20th anniversary of a landmark crime law that created the federal COPS grants program, which funds community policing in cities around the country.

London, England (CNN) -- Forty years ago London's docklands were an industrial wasteland. The shipping companies had moved to deeper waters, factories were left abandoned and poverty was rife. It's hard to believe that in just a few weeks the very same East End docks will be transformed into a St Tropez-style luxury marina worthy of the world's A-list celebrities. The mega-rich and their superyachts are set to descend on the regenerated Docklands for front row seats to the 2012 London Olympics. And high-end companies are keen to ensure no expense is spared when catering to their every whim. The exclusive experience will include helicopter transfers, speedboat taxis, a specially-constructed beach and even pontoons with private jacuzzis. Watch: The exclusive world of superyachts . "It will be a mini Monaco," Benjamin Sutton from concierge service MGMT told CNN. "In terms of location you can't get any better. We're opposite the Excel Center which will be hosting the gymnastics, basketball, wrestling. We're 5 minutes walk from the Thames Cable Car to the O2 Arena in Greenwich. And the Olympic Stadium is a 10 minute drive away. "We have preferential tickets to first class events like track and field. We tailor the package around the individual qualms of the client. Pretty much whatever they'd expect we can offer." The high-end service comes with a price tag to match. Berths are roughly £60 ($90) a meter per day, with a 70-meter superyacht setting you back a whopping £58,000 ($90,000) for two weeks of the Games. Celebs set sail . Among the wealthy expected at Wood Wharf, Canary Wharf, St Katharine Docks and Royal Victoria Dock in east London are Chelsea football club owner Roman Abramovich. The oligarch's superyacht Eclipse - believed to boast two helicopter pads, 20 jet skis, two swimming pools, hot tubs, a dance floor and a cinema - was previously chartered by music star couple Beyoncé, 30, and Jay-Z, 42. "There is a rumor that George Clooney will also be arriving," Benjamin revealed. Though he was quick to add: "But we can't reveal for sure who is going to be there. Privacy is very important." Watch: Designing superyachts . And when the superyacht owners come out to play, nearby restaurant and club Waterside House will be offering them the exclusive, high-end entertainment they've come to expect. A £1,000 membership will get you into the club's Black Card lounge for the duration of the Games. It includes access to a specially built 60 meter beach and nightclub where DJ Fatboy Slim is expected to perform. "It means by definition that the rest of the marquee is also extremely exclusive." Waterside House founder and director Ali Warburton told CNN. "These are very, very high-end clientele. We've got Olympic contestants, oligarchs, ambassadors, celebrities and CEOs of some of the largest companies in the world. "Superyacht owners are all over it. They're all billionaires and there's only a certain amount of time they can spend on their boat." London's docklands: From wasteland to luxury . It's a dramatic transformation for an area which in the 1970s had become a deserted wasteland. In fact, the grim image of a ruined city was the perfect setting for Stanley Kubrick's 1987 Vietnam war film Full Metal Jacket. The docklands had originally secured London's reputation as a great trading city and by the 1930s was the busiest port in the world. But with the emergence of bigger cargo ships in the 1960s, the shipping industry was forced to move to deep-water ports just outside London in Essex. By 1980 most of London's docks were obsolete. And it wasn't until the London Docklands Development Corporation redeveloped the site in the late 1980s -- including the financial hub of Canary Wharf -- that the docklands was reborn. Watch: The new home of sailing? The Olympic makeover is the latest development for this historic East End heartland -- one which Benjamin predicts could give it a lasting reputation. "This is an Olympic-themed platform to launch London as a future destination for superyachts," he said. "All these boats that used to go to the Med will now see London as a great place to stop off; a new launching pad for Europe."
