After European leaders stepped up military spending, President Trump aligned himself more closely with them on the war. But his tariffs threats have left bruises.

President Donald Trump made an announcement Monday aligning him more firmly with Ukraine’s defense against Russia’s invasion than ever before.

The U.S. has “realized that Russia does not really want peace, so in order to have peace, we need to support Ukraine and we need to put the pressure on Russia,” Kaja Kallas, the European Union’s foreign policy chief, told reporters in Brussels on Tuesday.

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

While Trump's new Russia policy announcement was welcomed by and large, there are still challenges ahead that will require more from America.
