zakariah host of "fareed zakaria gps," and richardhaus, president of the council on foreign relations and author of "a world in disarray: american disarray and the crisis of the world order." fareed, what has president trump achieved by saying the things he said about angela merkel just in the last couple of days? >> a lot of the behavior toward nato strikes me as not strategic. trump has nursed these grievances element since the 1980s. if you look at trump's writings, the few things he talked about when he talked about politics, there were two things. one, he thought that the -- he wanted to be protectionist. the japanese were ripping us off. later the chinese. but the second was our nato allies had been ripping us off, not paying their fair share. so this feels as though it's a long-held greechb that lon long-held grievance that he just can't stop himself from constantly expressing. even though it serves no real purpose. it doesn't help the united states. it doesn't help our strategy.
