The threats were topic number one when I sat down with Vladimir Putin in sochi. The entire region lockdown on high alert. These are Putin's games, and he's taking no chances. It is the largest security operation in olympics history but this morning, American officials are questioning whether Russia will be ready. President Putin promised me sochi would be secure. Translator: The job of the olympics host is to secure security of the hosts and visitors. We will do whatever it takes. The United States state department issued a travel advisory for all Americans heading to sochi and some of the athletes have even set up their own evacuation plan, own private security teams. Is that necessary? Translator: If someone believes that they should devise their own personal security plans, there is nothing wrong with that. However, it must be done in contact with the olympic organizers and with our security services. Services bolstered with 80,000 troops surround sochi with a ring of steel. But Putin insists this won't dampen the spirit of the games. Translator: We would try to make sure that security measures don't jump at you, are not in your face, do not put pressure on the athletes and visitors or reporters. Are you concerned that with all the security here the terrorists might choose to strike in other pars of Russia? Translator: We have adequate means available to us through the federal security service, the interior ministry, armed forces units that will be involved in providing security. On the water and in the air. If necessary, all those tools will be activated. But will they be enough? On this week homeland security chairman Michael Mccaul told me he is searching today to see the preparations for himself. All the briefings I received from the intelligence community and others indicate that there are serious concerns a. And that we need to do a lot to step up security. We have 15,000 Americans traveling to sochi for the olympics and I want to do everything I can to make sure it's a safe olympic. We saw that senator say he would not go to the games himself. I asked the same question of senator Mccall. He gulped and say that's why he wants to go to sochi. So much is riding on them. Clearly this is a high-profile opportunity for him to control the message. No question about it. He doesn't give a lot of interviews. Hadn't given an American broadcast in about four years. This is so important to him fighting for them since 2007 and needs them to be safe and successful. Thank you, great job.
