The US government already knows who you are (or can easily find out) and, US person or not, will make your life difficult if they decide to do so. Debanking, unofficial blacklisting, freezing assets, sanction lists, extradition, rendition, and even drone strikes are all options on the continuum. This is a nation that forced︀ down the President of Ecuador’s airplane because they merely suspected Edward Snowden was on board.︁ You do have to get their attention, either specifically or administratively, though. They aren’t generally︂ going to mess with you unless you catch their attention. The options on the more︃ extreme side of the continuum tend to require specific as opposed to administrative attention. To︄ use a popular saying, the US government generally can’t find its own a*****e with both︅ hands, but if it really wants to, can and will keep adding additional hands until︆ it finds AN a*****e. I know a venture capitalist who ran afoul of the US︇ government for his daughter’s political views and got hit with the first three on that︈ list.
This change increases the risk of administrative attention. It’s annoying but not really game︉ changing.
I‘ve been watching this. I tend to drag my feet until the last second︊ on complying with new regulations like this because they are often suspended or overturned due︋ to legal action. It’s a quirk of the US economy.
