In May 2012 Russian authorities claimed to have disrupted a major terror plot targeting the Olympics when they reportedly uncovered 10 weapons caches including anti-aircraft missiles, which they believed were destined for Sochi.
Dmitry Chernyshenko, a member of the Sochi 2014 Organizing Committee, said after those revelations that Russia is "ready for any scenario."
"Show me an event, any major event in the world, where security is not an issue... It's no different for us," he said then, before acknowledging the proximity of the Games to the traditional home for rebel leaders. "You know the situation in general is not easy in the world. That is why the host nation should be ready for any scenario. I know everything that is needed will be there to protect the Games."
The U.S. Olympic Committee told ABC News that American athletes' safety and wellbeing is "always [its] highest priority."
"No matter the event... we work diligently to keep our athletes safe," the committee said. "As with previous events, for the Olympic and Paralympic Games in Sochi, we will work closely with the International Olympic Committee, the organizing committee, our State Department and all other relevant government and law enforcement agencies to ensure that our entire delegation is safe while in Russia."
