President Donald Trump has finally found a way to like arming Ukraine: ask European allies to donate their weapons, and sell them American replacements.

President Donald Trump has softened his stance on NATO. He once called the Western alliance "obsolete." Now, he says, it's the "opposite of that."

Some conservative members of Donald Trump's "Make America Great Again" movement have reacted angrily to the president's plans to sell weapons to Nato, arguing it is a betrayal of his promise to end US involvement in foreign wars.

Donald Trump has said that US weapons are already “being shipped” to Ukraine as Washington ramps up its military support for Kyiv. A number of Kyiv’s European allies will purchase Patriot air defence missile systems from the US to assist Ukraine’s defence.

Trump agrees to sell billions in U.S. arms to NATO countries including Germany, Finland and Denmark and others for quick distribution to Ukraine, following his ultimatum to Putin on peace talks.

NATO Secretary-General Mark Rutte is set to meet President Donald Trump this week on the heels of the U.S. leader announcing plans to sell NATO allies weaponry that they can then pass on to Ukraine.

During a meeting with President Donald Trump, NATO Secretary-General Mark Rutte spoke about shipping new munitions to NATO.
