Most of Europe (notable exception france), Canada, and Australia will happily betray their own citizens to extradition to foreign countries. If things get bad enough that science immigration becomes 'defection' they'd be safer from the US in China.
Are you OK with a person committing a violent crime in a foreign country, then returning home to a country that "protects" them against extradition? I never understand the pushback against extradition. You can extradite carefully. Also, "most of Europe", Canada, and Australia are highly functional democracies. If extradition is so bad, why haven't they outlawed it?
Also, most people overlook the fact that, "any French citizen who commits a crime according to the French law, even abroad, can be prosecuted in France." So that makes extradition moot in my view.
