About-face on Ukraine? Trump surprises allies as he blasts Putin

Donald Trump has surprised Ukraine and NATO allies with an apparent about-face on Russia at the annual opening of the United Nations General Assembly in New York. We ask why the US president suddenly thinks Kyiv can win militarily, the same Trump who up until now blamed both sides for the war and most recently assured that Russian drones fired into Poland might be a mistake. We also ask what concrete steps to expect for Ukraine, and also frontline NATO members like former Soviet state Estonia after last weekend's 12-minute violation of its tiny airspace by Russian MiG fighter jets.
