Though Trump's decision was welcomed by leaders in Kyiv, Ukrainians and their supporters abroad also raised concerns that the 50-day window may offer Russian President Vladimir Putin an opportunity to intensify his long-range strikes against Ukrainian cities and ongoing summer frontline offensive.

Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.

In an announcement from Washington, U.S. President Donald Trump revealed that America will send top-tier weapons to Ukraine. The military aid will be delivered through NATO countries and includes items like advanced missiles and ammunition.
