Mainly because it's damned good duty in all of these places, Alan. Makes the military more attractive, especially to guys who are young and horny.
Oookay.
So why do American troops have to be there in these countries?
I guess we’re all bit touchy about others taking our stuff.
Still, with the likes of Iran and their funding of Hezbollah, the crazies in N. Korea, and the murderous Saudis, not to mention the military industries everywhere willing to sell anything to anyone(no background check needed,) having horny soldiers in far off places might not be such a bad idea.
