And we have a government that is more than capable of doing so. And government or not, there are more than enough armed civilians in this nation to make sure that any attempt by your nation at “retaking the colonies” would fail spectacularly. That latter point is probably what pisses you off, the most.
Britain was once a great worldwide empire, but now it's just a pimple on the face of Europe. And we, one of your former colonies, could easily end your nation's existence as a sovereign nation, if we had the will to do so.
Your posts, loaded with hubris and ignorance, tempt me to wish that we would, that America would invade the UK, turn it into an American colony, and oppress you the way you once tried to oppress us.
