David Cameron has given a speech in which he essentially compares current day Russia with the Nazis. He has explained how Russian actions (or supposed actions) in Ukraine are similar to Hitler’s invasion of Poland and Czechoslovakia. And the invasion of Belgium by Germany in 1914.
Apart from anything else this is sheer nonsense historically. Under the Nazis, Germany launched an aggressive war against all of Europe, and Russia. Russia has taken back Crimea. A territory which was part of Russia very recently.
