People routinely - well, at least every few months - shoot up US schools. They are radicalized online. There is a common pattern to the radicalization. However, it's ""forbidden"" to point that out or suggest restricting the supply of firearms to internal enemies of the US in any way.
Americans don't need any encouragement from foreign powers to do that. Congress has seen fit to keep letting it happen by pointing to ancient scripture about the right to develop one's own organized militia....
Difficult to be sure what would happen in a counter factual universe without foreign interference.
We do know that Russia et al sow division online as part of their anti western efforts, a strategy detailed in their "Foundations of Geopolitics" manual.
Someone commented, and I paraphrase poorly, "Imagine if Russia didn't influence the voters in 2016; all the racism and bigotry in the USA would disappear!"...
If we take precedent from other times children in the USA were slaughtered in schools, probably a bit of national grandstanding on either end of the political spectrum then nothing actually material happening.
They'd probably go all in, kill the leader of the nation, kill some of the successors in line, bomb the daylights out of a bunch of civillian sites, wipe out a girls school, sink a few ships... oh wait.
Iran is a state sponsor of Islamic terrorist groups worldwide and have contributed to thousands of deaths, including children. None of it is justified but let's not pretend it's one sided.
The US can't even confirm how many detainees have died in custody in immigration detention around the country, yet they have precise numbers on how many people the Iranian regime has killed? Give me a break.
If Iran is unwilling to let neutral international observers confirm the number, that suggests they are trying to hide a number they don't want the world to know.
Who gets to define what "neutral" is? According to the US, the International Criminal Court is not fit for this purpose. It certainly can't be a nation-state that's in a military alliance with the US.
Human Rights Watch, MSF, UNICEF? Woke grievance factories, the lot of them /s . World Health Organization? US just left it. It's slim pickings out there.
Which Iran did not do. There's a single report from an anti-Iran agency saying that Iran claimed 3,000 killed protesters (not 20k-30k). Iran never said that though, and I would challenge anyone to produce evidence that they did.
I find those numbers hard to believe, as it is obvious that the US was already planning a regime changing intervention for quite some time when those protests happened.
You can't trust people who paint Reza Pahlavi as a paragon of human rights and democracy. And neither you can trust every iranian refugee as a lot of those were corrupt members of the ruling government or worse, Savak members.
