So let's review
France is burning, Britain is in complete legislative paralysis, and the US is too corrupt to do anything except bomb other countries into anarchy and afflict the country with the religious whims of a small minority.
What the hell is going wrong with Democracy?
Someone famous said recently that Democracy has to be protected or it can decay... I don't remember the actual quote or who said it.
The recent blitz of bad news in the past ~3 years seems to have been a direct result of Russian intelligence efforts and Russian money. A lot of the cold war era bad news seems to have been a direct result of what you just said: the US fucking up perfectly good democracies.
If its any consolation... non-democratic regimes seem to collapse more quickly then democratic governments. Economically democratic countries do seem to slow the consolidation of resources into a small number of hands and thus keep democratic economies stronger. Much as it might seem like that's not the case, remember that the worst economic inequality is NOT in democratic nations, also the US has survived ~250 years of rich people trying to take everything, which is longer than most modern governments have continuously existed. Hell, as much as Russia might seem like they're kicking our asses, Russia is hurting too.
