First of all, the 2500 was just what they'd initially admit to. If you read on just a tiny bit, you'll see this:
The NRA later said that it had received more money from two Russian nationals previously disclosed, including Alexander Torshin, a Russian banker, with links to the Kremlin.
At the time, Torshin was under an FBI investigation into whether any Russian money was funneled through the NRA to help Donald Trump in the 2016 election.
Second of all, I'm not trying to whitewash American fascism. That they're cooperating with Russian fascists makes them WORSE and also more hypocritical for all their bigotry that they call patriotism.
It would still exist if American society was surrounded by vacuum.
Not true. If American society was surrounded by a vacuum, everyone would suffocate, including the fascists.
APAIC exists solely to support a foreign state. And laws were changed specifically to allow them to do that.
