Dan Caldwell argues that it’s prudent for the Trump administration to pause weapons to Ukraine, where he believes there are “limited U.S. interests at stake” (Letters, July 7). Thankfully President Trump now sees what Mr. Caldwell doesn’t: The outcome in Ukraine matters, and Vladimir Putin responds to concessions with more attacks.
The Ukraine war is part of a broader and more dangerous competition with an axis of aggressors—China, Russia, Iran and North Korea—that is underwriting Mr. Putin’s aggression. Sustained support for Ukraine while expanding our defense industrial base is the best way to realize Mr. Trump’s vision of peace through strength.
