Flatus,
Comparing Hitler and Saddam is perhaps tempting, but in 1938 Hitler had already re-taken the Rhineland, undertaken an illegal Anschluss with Austria and had re-taken the Sudetenland and then the rest of Czechoslovakia. His rhetoric made it clear that he was bent on further expansion by military means, not least in Poland.
By contrast, America thinks that Saddam may use his weapons of mass destruction against some unspecified target at some unspecified time in the future.
December 1940???
On another thread I've outlined my objections to getting behind the USA too readily. As a very junior partner we will associate ourselves with US positions which we do not necessarily share, which is why it is vital that America modifies its position on these issues.
That might even lead to an increase in public support for such an alliance and for military action, which the polls show to be very low right now.
