I'm not trying to take your guns away, but you must realize, they are a severely outdated means of attaining, power, control, and independence, on any meaningful scale, unless you're just trying to dominate some weak peaceful people or defend yourself from gangs and pirates (which is a real possibility), the 2nd amendment is completely outdated, and should've included modern technological rights... That's what guns were all about back then, new technology that could guarantee a fair fight for freedom. The real wars of evolved governments these days are not fought with guns... Have you heard of the bacteria in feline urine that infects the brains of mice, causing them to become attracted to the urine, as opposed to, repelled? Just try, seriously, just try to imagine what people like Gates are working on (he just released GMO mosquitoes in Florida a couple months ago, mosquitoes that will make people sterile, or otherwise, susceptible to the next part of the formula), and realize, they don't need any guns, it's genetic, biological, ecological, their means of domination and control, the zombie apocalypse is real, but nobody will even realize what they are.
People like Gates won't care cause they already feel like they're surrounded by morons, but then, they'll have complete control of us, and we'll build them some pyramids, as if it's an honor to die at the age of 30 doing so... The circuit to other realms will be rebuilt and a new era will begin.
There are plenty of countries out there that don't have a gun in every home yet they aren't being invaded and infact they get in less wars..ironic huh. It's like having a girl who wants a meathead to "protect her" sure that guy can bench press a lot and may know how to fight but he's also going to put her in more situations that a normal boyfriend wouldn't that would cause her to need "protection" So yeah you're right no one would be stupid enough to invade the US head on gun for gun..... but they will find other ways to take us down that will put the citizens in more danger.... And to add on to this, there would be nothing stoping a country like Japan from making a gun for everyone of their citizens in which case your argument is even sillier because we would be out gunned......(but again guns=irrelevant).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
