We actually do nab people who break the law in countries we can’t extradite from. People identified working in APT (advanced persistent threat) groups get labeled and watched, then grabbed when they travel to a country where the USA or affiliated can extradite.
It normally happens when they go somewhere warm for a vacation.

And some countries, Israel for example, have actually sent assets to other countries to flat out kidnap and smuggle them out. The (probably) most high profile example of this being the abduction, confinement, and smuggling of Adolf Eichmann by Shin Bet and Mossad personnel. There are films about this, one being Operation Finale.
