Sorry, but isn’t the second amenent about the right to bear arms? If so, what does that have to do with the US entering the war or making A-2 jackets? A lot of country did so without having this in their constitution. Many enemies were more than willing to step on US soil, they just never got close. Not because civilans had guns, but for many other reasons. Sorry, I’m just lost a bit and can’t really see the point you’re trying to make, nor how it’s all connected.
