The US has kidnapped people from Italy, and assassinated its own child citizens. The US (and most western countries) are already close to this, it's just that most citizens felt they were immune up till now.

This kind of overreach should always be opposed, no matter who it is done to, or where, because once it is acceptable to assassinate people with missiles, kidnap opponents, or record everyone's digital life whenever information crosses the border, all it takes is the wrong sort of people to take power and all the mechanisms are in place to control and oppress entire populations.
