To appreciate the dramatic shift in President Donald Trump’s policy towards Ukraine, consider two scenes in the Oval Office, months apart:

The way to get a peace agreement is to change the battlefield.

The latest bombardment in Russia’s escalating aerial campaign against civilian areas came ahead of a Sept. 2 deadline set by U.S. President Trump.

In December 2022, President Joseph R. Biden Jr. agreed to give Ukraine a Patriot missile battery, an advanced ground-based air-defense system. Two more followed, along with an unknown number of interceptor missiles that have provided the only effective means of shooting down Russian ballistic missiles.

President Donald Trump has reverted to his first-term foreign policy posturing, which was generally pretty great from a conservative perspective.

The president’s much-awaited “big announcement” gave Vladimir Putin another dangerous pass as Russia continues its summer offensive against Ukraine.

American fatigue with the war and the fickleness of the Trump administration remain concerns for Ukraine’s leaders.

Vladimir Putin’s conduct has prompted Donald Trump’s shift as Russia’s war effort in Ukraine has gotten only more aggressive.

President Trump now wants to give more weapons to Ukraine and is threatening increased sanctions if Russian President Vladimir Putin doesn't agree to end the war in 50 days. The president explained why in a phone call with our partners at BBC News.
