As President Donald Trump shifts toward a tougher stance on Russia, his special envoy Keith Kellogg met with Chabad rabbis in Ukraine.

Trump's moves underline his growing disenchantment with Russian President Vladimir Putin over the lack of progress in U.S.-led efforts to secure a ceasefire.

Donald Trump privately urged Ukraine to strike targets deep inside Russia, including Moscow, if supplied with advanced US weapons, signalling a pivotal policy shift in the war and raising stakes for Nato and Kremlin escalation.

Bolton told Newsweek that Trump's pursuit of a Nobel Prize has clouded his foreign policy, particularly on the war in Ukraine.

When asked about missiles for Ukraine, he replied that they were already being shipped. Read also: Berlin, Washington near deal to send Patriots to Ukraine “They’re coming from Germany and will be replaced by Germany.

Trump's threat against Russia runs parallel to a Senate-led effort to pass crippling sanctions on countries that buy Russian energy.

One of Vladimir Putin's mouthpieces has warned Donald Trump that he is pushing Russia towards nuclear war. After pledging to deliver more weapons to Ukraine - including the prized Patriot air defence systems - the US president rattled the Kremlin further and threatened to unleash additional sanctions if Putin refuses to negotiate a ceasefire deal 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.
