First, there’s nothing illegal here. He didn’t violate any US law that I can see.

Reality check. Sex tourism is illegal and particularly with children it is prosecuted.
The FBI maintains offices in many foreign countries now to bring our offenders back to the US with less fuss. Look for missionary blogs from poorer asian countries and the topic of child brothels and the effort to rescue the kids comes up a lot.

If a U.S citizen or resident is having underage sex abroad it is a federal crime under the 2003 PROTECT Act and subject to a maximum of 30 years in jail.

That's quite interesting, for a variety of reasons. If a pharmaceutical company did clinical trials in another country that allowed experimentation on patients without full informed consent, and thus was not breaking a law in that country, they would be nailed to the cross here (rightfully so), no matter what the letter of the law says. The news media would be all over it, incessantly, until heads rolled. I don't care if he didn't break any US laws. This identifies him as a predator with no well-defined ethical core. Situation ethics are to some extent worse than no ethics. At least the unethical person who acts that way all the time, non-contextually, is consistent.
