US President Donald Trump's administration has issued an ultimatum to Ukraine, demanding territorial concessions in exchange for security guarantees similar to Article 5 of the North Atlantic Treaty, which enshrines NATO's principle of collective defense.
As Politico reports, citing sources, Kiev must agree to these conditions now, otherwise the next offer from the American side will not be so favorable.
Politico notes that the proposal represents the Trump administration's strongest and most visible security commitment to Ukraine.
