it's a pretty big indirect attack. it's also not simply a reflection to the wall between the united states and mexico that could happen. but about american immigration policy. wolf, this is a very different president and a very different united states. and the trajectory of european societies is very different than the trajectory of american society suddenly. so there's a big gap. it's very different than the president's trip to the middle east. there the saudis in particular, also the israelis were relieved it was no longer barack obama, someone they'd lost confidence in. instead was donald trump. this is 180 degrees different. this is a group of people who by and large feel more comfortable with barack obama and what he represented and this is a very different president, a different country and you could just sense the political and almost cultural gap in the room today. >> richard, once again, the author of an important book" a world in disarray."
