Kim Dotcom made the mistake of operating servers in the US jurisdiction. New Zealand made the mistake of complying with the US requests to extradite him. The US could not have effectively enforced its laws upon Kim Dotcom without New Zealand's assistance.

If China comes after me for something terrible I say about Mao (stray absurd example), and the US turns me over to China because they're influenced and or intimidated by China, that would be a similar premise: the US would bear immense, near total responsibility for capitulating, showing no backbone.

I'm definitely not defending US jurisdictional overreach.
