US President Donald Trump's peace plan for Ukraine is taking shape, with a leaked document outlining key points. The plan, which has been criticized by some Western and Ukrainian security experts, involves a ceasefire, the withdrawal of Ukrainian troops from Russian-controlled areas, and the recognition of Russian sovereignty over territories currently occupied by Russia. The plan also calls for international peacekeeping forces to be deployed outside NATO. The plan has been criticized for its unilateral nature and for potentially leaving Ukraine vulnerable to future Russian aggression.
