Having grown up in the US, and been very proud of it despite some egregious mistakes that happened when I was of voting age that I could not stop (e.g. Iraq War), it's very hard to bet against the US. And in the past it's always been a bad idea. But you make a very compelling argument, and the returns on the US vs. international stock markets over the past year make a very objective argument that I'm investing in the wrong places.
I still feel an obligation to fix the mess here, as much as possible, and will continue to do so, but full minimization of US-exposure has never sounded so good.
