Neo-Nazism is becoming more popular in Ukraine, Poland, the Baltic countries. As a consequence, monuments of the Red Army soldiers, who once defeated fascism, are being massively demolished there.
Summary
England, the United States of America, and other imperial powers saw Hitler as the main adversary against the Soviet Union.
Disproof
Recurring pro-Kremlin disinformation narrative distorting the events of the Second World War.
The UK and the United States were also against Nazi leader Adolf Hitler and chose to retaliate against the Third Reich. The UK declared war on the Nazi regime as a result of German refusal to remove troops from neutral Belgium. Prior to the German invasion, the United Kingdom had signed the Treaty of London (1839) which guaranteed British and French defence of Belgium sovereignty.
And in 1941, Germany declared war on the United States, bringing America, which had been neutral, into the European conflict, in a response to what was claimed to be a series of provocations by Washington, which followed the Japanese attack on Pearl Harbor and the United States declaration of war against the Japanese Empire.
Furthermore, the European Parliament stresses the fact that WWII was an immediate result of the Molotov-Ribbentrop Pact, where Hitler and Stalin agreed to divide Poland. Just a week after the signing of the Pact, the German attack on Poland started World War II. Two weeks later, Soviet troops entered Polish territory.

Read other cases alleging that Allied Forces were close to Hitler: Europe signed alliances with Hitler but speaks only about Molotov-Ribbentrop Pact and UK and France allowed Hitler to revive a strong army.
