“We celebrated the 80th anniversary of D-Day. It was a failure. It was the 'unnecessary war, ’ described by Winston Churchill. We had a dozen chances to stop Hitler. It’s not about NATO. It’s not about American weapons in Ukraine. It’s about a megalomaniac wanting to create the Russian Empire by force of arms.”
Churchill didn’t think the war was unnecessary because the Germans should have been allowed to do what they wanted
