The most important salient point you have missed is that the USA is a democratic country and, as such, can bring any nut case in its country to heel by democratic means. That is why the Free Word was able twice,and at great cost, to overthrow a country like Germany which was, for the second time in a century, under the control of despotic thugs.
This is the wonder of democracy, that inhabitants of non democratic countries are incapable of comprehending.
It seems your understanding of democracy is seriously deficient and needs an urgent update.
You should seriously consider attending a night class, which will teach you all about democracy assuming, of course, that you really do live in a democratic country.
