"Most are there for a better life." No, they're there b/c they decided they won't sit back and be passively slaughtered in their streets. They don't want anymore 9/11's. That's it.
"For an education." I know personally a great many, and they probably have more education than you do, as they have more than average citizens. But there are some who want to serve first, and get an education later.
"The majority are from poor sectors and see no way out of poverty, other than joining the military." BS, bs, and bs. I'm from anything but a poor sector (but your class-baiting is noted), and I personally know one who has a sizeable fortune and business opportunities waiting for his return. He's 20 yrs. old and believes the best use of his time at this point is spent helping to defeat people who want to destroy what we have here.
"Aggressive recruitment capitalizes on this." Recruitment is being hampered. Most GO TO the recruiting offices.
"You're speaking for all of the troops?" Yes. I personally know and speak as part of a vast membership on a Pro-troops site. It's one of the most active forums that exists.
"Some may want to go back." Most of them do, that I've talked to.
"But not all." Yes, and believe me on this, the ones who don't, they can't wait to ship them out. FAST. You can be sure of that.
