Registering a .com through a EU-based registrar doesn't change anything.

Verisign, the organisation that actually controls the .com top-level domain, is a US company and operates under US jurisdiction.

Where you purchase the domain from is irrelevant.

That… is true - thanks for editing your comment to clarify

The initial thread read like “.com domains are exclusive to US” which they of course aren’t

		It's a bit like .gov and .edu; technically exclusive to the US. The difference is that .com and .org were opened up for anyone to purchase. And it goes deeper than just intent: .com was literally administered under a US government contract for decades, with Verisign only ending up in control because they acquired the company that held that government contract. So while anyone can buy a .com today, the infrastructure and oversight have always been firmly American.
