Why do countries find it necessary to go to war over an ideology?

Answer

Countries never go to war over ideology. The ideology is just a convenient excuse to sell the war to the citizens. Look behind the ideology for the real reason.

Example: Hitler didn't invade the Sudetenland because Germans needed "Lebensraum." He did it to increase his own power and to stimulate the economy of a country that was in a severe economic depression. But Lebensraum sold better.
