In my opinion, that in all reality, the constitution was never intended to support a large central government with the powers it has today. I believe it was merely intended as a central support structure for independant states to protect their interests in freedom/rights, trade and mutual protection. There origionally wasn’t to be any real hard legal power over the states like there is today. In essence all they were questing for was a central form of rights that could be had by all people of all the states, that the states would adhere to and provide eachother with protection from outside agressors. The current government has outgrown the origional intent, and in some ways this is good and in others it is bad. I don’t think any of the states back then would have signed on to our current form of government today. They would have ran away from it screaming and flailing their arms. Oh and I just took another look through the constitution and I didn't see anything in there barring seccession.
Germany’s first and foremost mistake even before the war began was Hitlers interference in the war planning. He thought he knew it all and was an arrogant egotist when he didn’t know jack squat about war tactics. Second mistake was they relied on an idiot that didn't know how to fight a war either, Mousolini. Personally, as far as Britian goes. I always thought they would have been better off instead of going after the RAF, sending the Luftwaffe after all allied shipping they possibly could. The subs would have been much more effective if the Luftwaffe were more engaged in scouting/attacking naval targets. If the British didn't have any fuel from the U.S. to fly their aircraft the RAF wouldn't have been a problem. The Luftwaffe's 2nd blunder was the fact that it relied too much on light bombers and light fighters. They vested too much into "super weapons" to make up for the lack of heavy fighters and bombers and multirole aircraft like the U.S.'s B-26 Marauder and P-47 Thunderbolt. And that is where Germany took the most beating were the marauding aircraft like the P-47 and P-51 that could carry 500lb bombs and rockets as well as dogfight. Shooting down their adversaries then spelunking the area for targets of opportunity. That killed germany's industry and infrastructure more than the B-17's did. The Luftwaffe's 3rd mistake was not taking it's elite pilots and turning them into trainers for the new recruit pilots like we did. They suffered for it later in the war. Germany could bring the firepower into the skies, but they just couldn't translate that firepower into the ground, where it really counted, to destroy industry and shipping and other critical pieces of infrastructure in Britian. As far as Russia goes, whether Germany attacked them or not I suspect that Russia would have been a problem for them anyway and that the best they probably could have done in the long run was keep russia back out of Europe.
