Nazi Germany stood a reasonable chance of winning WW2. They made many mistakes as well as underestimating the resistance that Britain would provide, but victory was certainly feasible through 1941 or 1942.
But it seems, certainly, from the perspective of 1930s, WWII would mean for them attacking a coalition of Poland, France and UK, and attacking Russia and USA down the line (I understand this was always the plan). UK and France were the two dominant superpowers of the era, with US on the way up.
It's not, IMHO, incomparable to the current situation. Only a madman would attack the "West", be it NATO, EU, or its allies in Asia; the chances of victory are perhaps not negligible, but expected gain certainly very poor. But it seems there's something in human history to disregard such calculus and plough on regardless.
That's certainly fair, and a definite delta from your previous "probably not, or a slim chance" statement. Thanks for considering alternate views.
> The high-ranking German military leaders believed that if Hitler invaded Czechoslovakia or any other country, Britain would declare war on Germany.[52] MI6 was of the same opinion. The British declaration of war would have given the General Staff, it thought, both the pretext and the support for an overthrow of Hitler, which many of them were planning because of the prevailing "anti-war sentiment of the German people".[53]
