The Pentagon has dismissed Poland’s plan to hand its MiG-29 fighter jets to the US, to donate them to Ukraine. The Polish foreign minister, Zbigniew Rau, said his government was “ready to deploy – immediately and free of charge – all their MiG-29 jets to the Ramstein air base and place them at the disposal of the government of the United States of America”, amid intelligence agency warnings that Vladimir Putin is about to “double down” in his invasion. However, the Pentagon appeared to reject the proposal, saying it was not “tenable”. The US Department of Defense said the prospect of the jets departing from a base in Germany “to fly into airspace that is contested with Russia over Ukraine raises serious concerns for the entire Nato alliance”.
