The reactions to the Trump administration’s decision to pause some weapons shipments to Ukraine couldn’t be more illustrative of the conflict: welcomed by the Kremlin, branded “inhumane” by Kyiv.

It was the latest in a series of almost weekly large-scale missile and drone attacks. President Trump said he “didn’t make any progress” with President Vladimir V. Putin of Russia.

A record 539 drone and 11 missile strikes hit Kyiv hours after a phone call between the U.S. and Russian presidents.
