New developments Tuesday reinforced the idea that President Donald Trump has significantly shifted his view of the Ukraine war.

Ukrainian President Volodymyr Zelenskiy also held talks with a U.S. envoy on Monday on increasing weapons production and arms purchases.

President Donald Trump is downplaying the possibility of sending Ukraine long-range weapons as Kyiv awaits an injection of U.S. weaponry that it hopes will help it beat back an intensifying Russian air offensive.

President Donald Trump’s ultimatum to Russia to accept a peace deal in Ukraine within 50 days or face bruising sanctions has given the Kremlin extra time to pursue its summer offensive.

In a statement, NATO said NATO Secretary General Mark Rutte will be in Washington on Monday and Tuesday and meet with President Trump and key administration officials.

On Monday, Trump said that Russia's failure to reach a negotiated settlement with Ukraine within 50 days would lead to his administration imposing a 100% tariff rate on Russian imports as well as what he called "secondary tariffs" on countries that have continued to do business with Moscow.

As President Donald Trump hardens his position toward Moscow and seeks new ways to bring the conflict to an end, he is leaving open the prospect of allowing shipments of longer-range missiles to the country that would allow it to strike deeper into Russia,
