The third Republican presidential debate Wednesday night was useful in many ways, and especially in revealing the emerging GOP fault line on foreign policy. Nikki Haley and Chris Christie stood out for supporting Israel and Ukraine and scoring President Biden for weakness that invited aggression from adversaries. Vivek Ramaswamy showed himself to be a full-throated isolationist, while Ron DeSantis and Tim Scott were hedgers, especially on aiding Ukraine.
Front-runner Donald Trump again was a no-show as he tries to persuade everyone that the campaign is over before anyone votes. His foreign-policy views have turned in a more isolationist direction since 2020, to the extent he’s clear about anything. His main argument is that no wars began while he was President, so no wars will begin if he’s elected again.
