As Volodymyr Zelenskyy seeks to undo the damage of the Oval Office confrontation, the question is not just how far but how fast the Trump administration moves

How long do Ukraine and Europe have to respond to US betrayal? When Russia launched its full-scale invasion three years ago, each day that Kyiv held out was a victory. The west rallied to Ukraine’s support at equally remarkable speed.

Now, as the Trump administration turns upon the victim, and embraces the aggressor, Europe is accelerating nascent plans to bolster Ukraine and pursue security independence. Trump allies blame Friday night’s extraordinary Oval Office confrontation between Volodymyr Zelenskyy, Donald Trump and JD Vance for the shocking halt to all US military aid. Others suspect that the administration was seeking a pretext for the suspension. Mr Zelenskyy pledged on Tuesday to “work under President Trump’s strong leadership to get a peace that lasts” and expressed gratitude for his first-term approval of Javelin missile defence systems sales.
