1. This contention shows that you know nothing about how Germany went about invading other countries. 'Blitzkrieg' was not about sending troops in first, but the opposite. Aerial bombardment coupled with tanks going in was the method of killing/demoralising the population being attacked. Troops then followed in the wake of the total disorganisation that followed. A country's military machine was the ONLY way to prevent invasion, not the general populace. To believe anything else shows you are thick...
2. In the light of my first paragraph above, it is not only a hypothesis, but 100% incorrect. The rest of your second paragraph is therefore fatally flawed as a premise.
3. Everything you have stated IS disturbing. You off NO new perspective at all. You are a right-wing gun nut who sees no problem in laying the blame anywhere other than where it should be placed. You, and all the others in American society who think like you, are a cancer on that society which, unfortunately, will never be eradicated.
By the way, don't take me on about WW2 - I've probably forgotten more than you will ever know...
