Personally, I think it would be in the news for a couple days and then most Americans would pretty much forget about it and move on. Some folks on the left would point out this is further proof we need to abolish the CIA. The US Senate responds by a 98-2 vote to increase funding for the CIA, because white suburbanites are now scared the CIA will be eliminated and brown people will start bombing their big box stores.
They couldn't do it yet. There's plenty of boomers still alive for whom it was a formative political experience. I think libs would become Outraged Online but then not do anything about it.
I think leftists would become Smug Online and then continue to not do anything about it.
