But there are other Trump positions that are deeply disturbing, if not outright offensive to the kind of non-interventionists (or “cosmopolitan realists”) who have filled the ranks of Cato’s foreign policy program. Trump’s hostility to free trade is both disappointing and myopic. But his stance on immigration is even worse. His proposal to build a wall along the border with Mexico to keep out undocumented Hispanic migrants is not only impractical, it conveys a message of hostility to such populations. Trump’s stance on Muslim immigration, especially his call for a “temporary” ban, conveys such hostility with even greater clarity. His support for trade protectionism, combined with adamant opposition to liberal (or even reasonably humane) immigration policies and indeed his overall xenophobic rhetoric understandably alienate more cosmopolitan non-interventionists. What they may find difficult to admit, though, is that Trump’s type of insular, intolerant nationalism has a long history within the non-interventionist camp.
