What exactly did he do that suggests he didn't intended to fight the west.

I'm sure they did, especially after Hitler marched into the Ruhr DMZ in 1935, but they certainly thought that after Hitler took over Sudetenland and Austria that he would be content with his new lands. After they sacrificed the rest of Czechoslovakia that desperation for appeasement grew.

After September 1, 1939 they knew that Hitler wouldn't stop and so war commenced.

Germany was already violating their post-war agreement, by strengthening their military to that extent. At that point, the flashing red lights might not have been as clear, because the 1930's economic crisis was yet another obstacle to deal with.

That's for sure, when the French surrendered he had them sign the papers in the train car where Germany signed its surrender following WW1. He then blew up said train car, just to be safe he wouldn't find himself in that irony again.

Hitler was never one to finish things. He was successful in the west and things seemed going well until he declared war on Russia. I wouldn't be surprised if he had ADD. Anyways, I personally think if Hitler and the Axis Power had dominated all of Europe for some time, he would eventually strike America. He was never one to keep his word or obey treaties and when he had the upper hand, he would sure use it.

It's a possibility when you consider that he injected meth to keep up his productivity. Stimulants such as ritalin (used for ADD) have a similar mechanism when released in the blood stream as amphetamines.

Hitler and the German General Staff realised that they MAY have to prepare to fight Britain and France sooner or later and a general war was pencilled in for 1944-1945, but the fact of Britain and France's declarations of war on 3 September 1939 took Hitler especially by surprise.
According to Overy, Blackwell, Irving and others, Ribbentrop, the "British expert" consistently informed Hitler and the other Nazi bigwigs that Britain would never fight over Poland and supported his opinion by witholding diplomatic and intelligence documents that refuted his position and using summaries of British political news soley from the Daily Mail and the Daily Telegraph. Goering, through his own intelligence network that spied on Ribbentrop among others; the Abwehr and the Italian diplomatic corps desperately tried to convince Hitler that the British WOULD fight, yet Ribbentrop's views prevailed and he was far more agressive with his threats to Poland than seemed prudent even to other Nazi leaders.
When the die was cast and a German invasion under way, Ribbentrop assured Hitler that Chamberlain was bluffing with threats of war and when the declarations were finally published ashocked Hitler asked a squirming Ribbentrop "What now?"
