You are right to be cautious. Hitler moved into Austria and then Czechoslovakia because Germany was out of money. Hitler's rearming of Germany and the infrastructure projects used up a lot of money. Annexing these countries provided foreign exchange cash and gold. The money went to Germany and was replaced with monopoly money. This was enough money to run their rearming for 2 years. Additionally, the Czech arms industry went straight to Germany, They made excellent small arms ammunition and tanks throughout the war.
I think that you may have missed the open mike tape where Kerry says that he'd love to have a war with Russia. If we weren't broke, we'd be fighting them right now.
