Helllllooooo??? Ahem! This kind of thing is going on all over Asia.
Was in the postwar occupations of the '40s. Was in the '50s. Was in the '60s and the 'Nam. In the '70s. In the '80s. In the '90s. In the new millenium. In 2012. The Asian "girls" willing to sell it to US military in dank, shoddy honkytonks and cathouses act and look much the same (excessive makeup, foul English gutter language, aggressiveness, probably rejects from their own society, looked down upon by males of the same culture, certainly not particularly cultured or mannered, and some looking for the ticket to the "Big PX") (US stateside) through some naive, young E-4, then bam!, splitsville.
You can see it from a distance (pickups) or witness inside a club or a bar, and you know darned well what is happening. Korea, Japan, Hong Kong, Thailand, Philippines, Guam, Malaysia. You name it. Where the US fleet lands or Army or Marines come ashore or flyboys land, whores by the thousands congregate like maggots. It is a sad story, but I am telling you, it is the way it is out in Asia near any US military base. Now what percentage of lonely young (and some not so young) men do this, I am not sure. Could be as low as 5%, I am guessing more on the side of 30 or 40%, maybe 50% in some places, and yes this involves married men with their wives back home. Much of it is "wheels down, rings off". It is just a fact of life. Recently in Korea they are trying to crack down on it, but I doubt little will change. And I should say, military from all other countries on maneuvers, TDYs, what not, also patronize the form of nefarious, stinking and sometimes dangerous nightlife. That's just the way it is. It might come as a shock to many back there in the USA. These are generally good, dedicated men doing a dangerous job, and when they want to let off some steam, well, they let it off. Bad? Yes. But who am I to judge. Its just a fact though. Sorry to worry any military wives out there. It does not surprise me the Secret Service has been active in this regard, and probably more places than Cartagena and San Salvador will emerge after its all over. You can count on the Libs to try to use this sad reality in some way to weaken either the Defense Department or the Secret Service.
