Syria Chemical Weapons: US Ready for Strike on Syria, Hoping for International Support abc's chief global affairs anser, martha raddatz. They're ready to go alone. But hoping to put together some time of coalition. Reporter: They are. Time is running out, george. The president wishes he didn't have to go it alone. But he's ready to do that. We have the warships, and cruise missiles, and a fifth destroyer packed with cruise missiles in the mediterranean. So much signaling that it will be a strike. That's giving the syrians warnings and ability to prepare and counter that. Reporter: There's reports out of syria, that the syrian regime is moving important people out of important buildings and airfields. And reports they are bringing busloads of other people in. That might mean they would have images of dead people they would say were caused by the bombs. Or try to use them as human shields. The other question, what kind of retaliation should the united states and the west expect in the event of a syrian strike? And you just came from israel, which is really going to be one of the first targets. Reporter: Yes. Just back from israel. The country most likely to be retaliated against is israel. And the prime minister, benjamin netanyahu said as much, which created a rush on gas masks. People lining up. It was really a chaotic scene. But officials do not think assad is crazy enough to try to retaliate against israel. One israeli told us, he is a bully to his own people, but afraid of the outside world.
