"Not our war" is the message from America's top allies this week, after President Trump asked them to help secure the Strait of Hormuz. Many NATO allies view his war on Iran as illegal, and, coming from a President who just two months ago was threatening Greenland, the request fell on deaf ears. Meanwhile, America's enemies may see a the situation as an opportunity.

He was also US Ambassador to NATO, and he joined Christiane in London.
