It is not correct that a law has to explicitly state that it is applied extraterritorially. Application of law and persecution is valid on both location AND nationality. That's what we learn at middle school civic classes. Gambling,punting,espionage, treason, terrorism,weed smoking,firearm possession with just permanent residence..etc.. there are many actual cases proving that way. A guy said here that Korean sex travelers go to jail because it is stated on that law that way which is NOT the case. It is just basic law theory which pupils learn at school. Predator UAV killing of terror suspects and Mossad killing terrorists overseas are somewhat different but good examples. Nothing states the basis of such actions specifically on the respective laws. Of course these two things were GOOD actions.I have seen many who smoke weed in Amsterdam then went to jail. Again, the relevant specific law does not state that this act(weed smoking) s subject to extraterritorial prosecution. Middle school civics is always a good startpoint.
A lecture by an active duty LAWYER on application of laws:

A lawyer knows much more and better than anyone here. He mentions gambling over small amounts and weed smoking. Another typical case is firearm possession with just permanent residence
In addition,in sex related cases, evidence is not required for guilty convictions.
Another very particular and peculiar case of law application:
