"Just consider: in many countries, the U.S. government has an open and active FBI office."

Most certainly. One country being actively monitored by the FBI is the Philippines. A country where a girl of 12 can legally have sex with any aged male. The US is actively trying to change this and other laws on the books to make do as US way and standards....regardless of age old traditions and such in foreign countries.

"The Age of Consent in Philippines is 12 years old. The age of consent is the minimum age at which an individual is considered legally old enough to consent to participation in sexual activity. Individuals aged 11 or younger in Philippines are not legally able to consent to sexual activity, and such activity may result in prosecution for statutory rape or the equivalent local law." https://www.ageofconsent.net/world/philippines
