That may be so, but maybe it's time for this to happen. People have simply had enough of watching the media and various levels of government bless Antifa/BLM rioting/killing/burning. Now the media and Congress are upset because the designated whipping boys, the Americans who have had to put up with all this shit for way too long, came to say "hello". Tough shit, fuck that and fuck them. They sowed the wind, now looks like they are reaping the whirlwind.
I look for this to continue, one way or another, for some time.
Antifa/BLM have behaved almost as predictably as the media itself, and people didn't feel like taking advantage of that to get one step ahead of them. They kept walking, face-first, into the wall. I see this more as that - you're going to get the Troubles at the best.
There's no universe in which this becomes something that wins more people over to your side, because the fundamental predicate - Trump was cheated - falls apart when you do the research yourself. I don't mean when you go to that collation or things that anyone can report to, I mean when you find the videos, you find the testimonies, you find the court cases, you autistically read through them all one after another. You do not come up with what Trump is saying happened, and this outburst is not marketing itself as anger at the DC political class on the whole. Because if Trump had won, this wouldn't be happening; this is their reaction to losing an election and believing that they were defrauded, which most of the country was already skeptical about. This action doesn't help that.
I take the contrary opinion: these concerns are now almost entirely too easy to sweep under the rug, this is used as a pretense for a massive crackback from the government figures, hopes of reform and devolution are scattered, and beyond a handful of small insurgents most of these people have no stomach to keep momentum going.
And while I don't think this makes the USA look weak, it certainly makes their politics look bad and bodes badly for the future.
A reality TV star convinced a massive portion of the population that all of the country's systems and processes and politicians were corrupt and bad, and the capitol building was stormed with extreme ease by a relatively small crowd for our population. Had the police been able to hold the line or had the protesters not stormed the building, then this would be a different equation; other countries would see us mostly how they've -been- seeing us, fairly unstable but not terribly unreliable. This is a national embarrassment whose only positive spin is if you truly believe it will be the opening salvo of a revolution, for which I am rather obviously skeptical. I see this moreso as the parties fundamentally realigning and the emergence of a third faction.
