President Donald Trump has made a major reversal on the Russian war, declaring Tuesday that Ukraine is positioned to retake all of its lost territory and more.

The dramatic change of heart comes just over a month after the U.S. president agreed with Russian President Vladimir Putin on a potential peace plan involving Ukraine ceding its land to the invading forces.

'After seeing the economic trouble it is causing Russia, I think Ukraine, with the support of the European Union, is in a position to fight and WIN all of Ukraine back in its original form,' the president wrote on Truth Social Tuesday afternoon after meetings at the United Nations General Assembly in New York.

'With time, patience, and the financial support of Europe and, in particular, NATO, the original Borders from where this War started, is very much an option.'

Trump noted in his lengthy statement that Russia looks like 'a paper tiger' that may not be able to support its lofty military ambitions with a depleted force. He claimed a 'real military power' would have been able to win the war in less than a week.
