what must the members of the g7 be thinking now? >> the large question looming over the g7 is the instability and slowdowns that a lot of countries are facing, including china, u.s. and germany and the question of president trump's behavior. during the last two g7s, they came away feeling president trump was confrontational and angry. you have him talking about the trade war. you have european leaders on edge. president trump is doing what he has been doing. he has everybody worried for what it means for america's role in the economy. a lot of countries looking to the u.s. for trade policies and want to look to the u.s. as a leader on international trade. foreign experts tell me america has pulled back from that role. >> john, in many ways was this clash with powell inevitable?
