Of course man, everything is 'just fine'.
Outside of the USA: talk of invading Canada, Greenland, indiscriminate execution of people on the high seas, a tariff war that seems to be a series of own goals, destabilization of NATO, the burning of 75 years of goodwill.
Inside the USA: military in the cities, half the country is being depicted as 'the enemy' by those in power, an embarrassing cadre of incompetents are in powerful positions and are wrecking the departments they are nominally in charge of, North Korea style adulation of an idiot leader, attacks on judges and members of congress are on the order of the day, teams of masked man snatch people (men, women, children) off the streets and out of their beds, endless violations of the law by the authorities, naked power grabs and abuse of pardons, attacks on the free press, destruction of the machinery of the state are the order of the day.
Those things you mention were bad, but they were still within the framework of the normal functioning of a state, it never looked as though there was a real chance of the USA fracturing or turning on itself no matter how bad they were. But this time it looks very much different. If you can't see that then that's fine with me but 'historical ignorance' is an easy card to play if you have already decided that what's happening right now in the USA is business as usual, and to me it does not look like 'business as usual' at all. This is unprecedented, and it is getting worse every day.
What I think is happening is that the 'flooding the zone' strategy is working so well that people are simply no longer able to keep up with all of the assaults and they hunker down, hoping that it will pass them by. That's a coping mechanism.
Again you are speaking from ignorance, and the inability to differentiate online bubble talk, shit talking by politicians, and reality. The Candian PM was sitting in the White House laughing with the president two days ago, are you seriously saying there is some sort of invasion threat? I don't like that twitter shit talking has bled into people's actual mouths, but I am capable of understanding that it is just talk.
George HW Bush deployed national guard to cities to deal with unrest, Lyndon Johnson deployed the national guard multiple times to deal with unrest, Eisenhower didn't just deploy the National Guard, he sent in the 101st Airborne - the real army. The current deployments are small and peaceful in comparison.
