Europeans don't generally use .gov so if the US tries to pull that, they'll just block whatever .gov their VPN is hosted on.

Southern European countries are blocking whole Cloudflare IP ranges because of the massive grip on the government the sports licensing maffia has there. These countries also don't feature any direct flights to America as far as I can tell.

These blocks may cause (temporary) issues for American business relations and tourism, but such side effects may not be considered so problematic if the US leverages their government infrastructure to attack European legislators.
