Judging from the lack of attention to foreign policy in this campaign, one might conclude that few security challenges loom. Other than immigration policy (more a domestic than an international issue), trade, and, occasionally, the Iran nuclear deal, the rest of the world has been largely invisible.
Yet overwhelmingly, the Republican leaders most distraught by Donald Trump’s candidacy are foreign policy and international security experts. In March, 121 of them stated their “united…opposition” to someone “so utterly unfitted” to the job. A second group signed another such letter in August. Others, including former National Security Adviser Brent Scowcroft, former Treasury Secretary Henry Paulson, former Defense Secretary Robert Gates, and former chairwoman of the House Foreign Affairs Committee Ileana Ros-Lehtinen, have independently announced their opposition. On a list compiled by The New York Times of the 110 most senior Republican leaders who have said they won’t vote for Trump, no fewer than seventy are foreign policy experts. . . .
