I think what Secretary Ash Carter is seeing, and I'm glad he is, is that we got to get NATO back working for the common defense. We've got to do more to support our partners in NATO, and we have to send a very clear message to Putin that this kind of belligerence, that this kind of testing of boundaries will have to be responded to. The best way to do that is to put more armor in, put more money from the Europeans in so they're actually contributing more to their own defense.
