Depends on how you define "quick." Germany had been moving quite obviously in this direction since at least 1935 (the Rhineland crisis) with a series of overt violations of the Treaty of Versailles ... and the allies neglected to respond to any of them.
Hitler gave orders that if the French so much as fired a shot when the Germans marched into the Rhineland, that his troops were to turn back. It never happened, and from the point on, Hitler knew Britain and France wouldn’t lift a finger to stop him.
This is correct.
We dodged a bullet because Bush went into Iraq. Iraq was building weapons that were clearly in violation of the Gulf War cease fire terms. As a minimum, missles were found that had a range that were in violation of the cease fire.
Bush may never get the credit he deserves, simply because Saddam hussein was never allowed to put his military build-up into action. Every now and then we do learn from history.
