Listen: On the GZERO World Podcast with Ian Bremmer, two starkly different views on Ukraine's future: first from the Baltics, then from Moscow.

In a war dominated by the unexpected, few imagined Ukraine’s fourth year at war would so firmly now question the security of all of Europe.

John Simpson, in discussion with the BBC's unparalleled range of experts across the world, analyses whether Russia’s war in Ukraine is nearing an endgame, examines the implications of the surge in support for the right in the German elections and looks at the huge increase in government surveillance under the Taliban in Afghanistan.

U.S. President Donald Trump is determined to bring an end to the war in Ukraine, which has cost hundreds of thousands of Russian and Ukrainian lives and billions of dollars in Western aid to Kyiv since Russia’s full-scale invasion of its neighbor three years ago.

According to the New York Times, US President Donald Trump's administration may stop all assistance to Ukraine, including indirect support. As reported by the New York Times on Friday 28 February, a Trump administration official said that all US aid to Ukraine - including recent deliveries of munitions and equipment authorised and funded under Joe Biden's administration - could be cancelled in the near future.
