I am only jumping into this thread for historical reasons. The comment on why Germany did not invade the US is somewhat inaccurate. It came from a post war interview of both Truman and a Japanese Minister of Defense or some title like that. He was asked why Japan did not invade Hawaii after attacking Pearl Harbor. His response was something like there was no military advantage to invading Hawaii unless you wanted to use it as a staging/fueling point to invade the rest of the US. Their (Japan's) intelligence determined that 1 in 3 or maybe 1 in 5 people in the US owned a firearm of some type. As result they felt like it would be stratigically foolish to go up against those odds while they were still fighting on other fronts. You also have to keep in mind that at the time bombing the US in preperation for a ground invasion was not really an option. The planes of the era required a carrier launch and their ability to carry on a bombing campaign would have been squashed long before they could have done enough damage to have a high likelyhood of success of a ground invasion. The bottom line the US was not invaded due to many reasons but private gun ownership was part of it. Now that I have cleared up history I need to go clean my S&W 9mm as it has not been out of the case in 6 months. What can I say, Us Texans like to own guns, even if we don't carry them.
