What role will foreign policy play in the upcoming US presidential election? “More than it usually does,” says Harvard Kennedy School’s Stephen Walt in an interview on GZERO World with Ian Bremmer. “Partly because the economy doesn't seem to be helping Biden as much as it should be, partly because it's hard to look at Biden's foreign policy and tout a lot of big success stories."

In a wide-ranging interview comparing US foreign policy under a second Biden or Trump term, Walt suggests that they may not be as different as people expect. “On a bunch of big issues, the daylight between him and Biden just isn't that great.” It may come as little surprise that Bremmer disagrees.
