A
 recent survey of U.S. foreign policy reveals a major change: For the 
first time in nearly five decades, a majority of Republicans say the 
United States should stay out of, rather than play an active role in, 
world affairs. The Chicago Council Survey,
 conducted by the Chicago Council on Global Affairs, found that the 
shift was led primarily by so-called Trump Republicans—the 47 percent of
 Republicans who held a very favorable view of Donald Trump.
Debates about America’s role in the world are hardly new; nor is the 
argument that Washington would be better off focusing on domestic 
issues. What seems new, however, is the concentration of people who hold
 those views not only in one party, but specifically within the 
pro-Trump wing of the GOP.
“It’s very important to understand that what’s happening is not some 
kind of secular change, or that America’s becoming more isolationist as a
 whole,” said Ivo Daalder, the CEO of the Chicago Council on Global 
Affairs, speaking on FP Live.
 “There is one major political force in this country, led by a singular 
individual, who has been able to mobilize a movement. Not that that 
sentiment didn’t exist, but it wasn’t this salient, and it wasn’t used 
as a means to mobilize political power. It is now—and that’s why it’s 
getting more attention.”
Daalder, who is also a former U.S. ambassador to NATO, explained why 
he felt Washington needed to overcome the Trump Republican consensus 
about not giving to Ukraine. “The United States needs to stand up, 
because we’re the only ones standing in the way of Ukraine losing—and it
 can lose the war. That would be a strategic disaster not just for 
Ukraine, not just for Europe, but frankly, for the United States. We’ve 
been here before. Big wars in Europe don’t end with the United States 
staying at home but with the United States getting involved in those big
 wars itself. That’s what happened in World War I. It’s what happened in
 World War II. What we want to do is to prevent World War III.”
