>> no, it hasn't. i think the implementation of the strategy is a little bit uncertain now because negotiations have failed. now, it's good that we pursued that, but i think it is very important that the administration have a very specific plan to change the dynamic on the battlefield. the administration deserves a lot of credit on the humanitarian aid, did i mention $1.7 billion, but also it deserves credit for the chemical weapons agreement, but they have to complete it and bring all of it into effect. but i'm really concerned now that we are at a pivot point, and unless we make it very clear that we're going to specifically help the opposition, those that are well-vetted, not the extremists, but those that are representing the legitimate aspirations of the syrian people, that if we don't do that, then we're going to have a bad result in syria. >> senator bob casey, democrat from pennsylvania, sir, thank you for your time today.
