You people ignore the fact that if Chamberlain had been 'honourable and gone to war over the Sudetenland in 1938 there would have been a state of war with Germany, which is a fearful thing, and it would have involved France and the Czechs as well as Britain.
No one is ignoring that. And going to war in 1939 wasn't a fearful thing?
You then assume that a German blitzkrieg would not have engulfed Holland and Belgium or France in 1938 because of weak little Germany . . .
Yes, because it wouldn't have. First, as has been pointed out to you, Germany had only three panzer divisions at the time of the Munich crisis. Second, and more to the point, there is no way that Germany could have gone on the offensive against France while fighting Czechoslovakia.
. . . and that the Czechs would have lasted more than three months . . .
Straw man. No one is assuming that. But even if they had only lasted three months, first, the Czechs would have held out until December, making it far too late for Germany to launch any kind of an offensive against France before winter, and second, considerable quantities of both German and Czech war materiel would have been expended in the fighting, and would thus have been unavailable for use against the Allies in 1939.
. . . and that there were no deficiencies in the British army or air force at the time.
Straw man. Again, no one has said that. The year's delay unquestionably allowed for the strengthening of the RAF. The point you seem unable (or unwilling) to grasp is that the year's delay, combined with the virtually bloodless conquest of Czechoslovakia and the signing of the Nazi-Soviet pact, strengthened Germany far more than it strengthened Britain and France. Further, as I've pointed out, and you've ignored, Chamberlain neglected the Army in favor of the RAF.
Churchill's attitude seemed to be to have a 'with what strategy' and to try to involve the Americans at the time, which was pie in the sky because of political and military problems in America then.
Churchill's "attitude" was presumably that the Allies would have to fight Germany eventually, and that it was better to fight sooner rather than later, which, as has been demonstrated, were absolutely correct. And Churchill had been in government during World War I; he was undoubtedly aware that it would take time for the US to build up and deploy significant land and air forces in Europe.
Chamberlain declared war on Germany. That's not appeasement.
Irrelevant. He clearly pursued a policy of appeasement prior to 1939.
