Nazi Germany re-occupied the Rhineland - another material breach that went unchallenged.

Nazi Germany annexed Austria - another material breach that went unchallenged

The Sudatenland was annexed, swiftly followed by the invasion of Czechoslovakia. I hate to correct Mr. Hartman but it was this incident in 1938, not the Annexation of Austria in 1936, that prompted the Munich Crisis that resulted in Mr. Chamberlain return to London with his "piece of paper" in his hand. Hitler was absolutely livid - he needed his war in the west that year - thankfully, for the entire world, he didn't get it, because in 1938 he would have won.

Here's where your comparison falls down, Teribus. When Saddam invaded Kuwaite, the world responded, and he was forced to withdraw back to Iraq. He has not invaded any other countries since then. The US, on the other hand, has been invading other countries; Afghanistan, and now Iraq, and it has its eyes set on eventual military action against countries such as Iran and Syria.
