the point where something accidental, not a deliberate decision by either side, but something accidental could really set it on fire. >> so you're saying this could be the excuse that putin would then jump on to potentially invade ukraine? let's remember how world war i started. >> well, you know, he looked at the american and european reaction to his military seizure of the crimea, and despite what we just heard from the administration, it was pathetic. putin has paid no price for seizing territory of another sovereign nation by military force, and i think he judges that the administration is all talk and no action. as senator mccain said, we've done nothing tangible to help the ukraine, and we haven't made russia feel any pain whatever for taking the crimea, so i think putin thinks he's got a clear field in front of him, if he chooses to act militarily. >> talking about putin remaining defiant against u.s. interests, what about iran?
