Now that was a pretty good question. However, it was also simple. A-stan has not been able to be utilized as a staging area by any Islamic Terror group to launch terror attacks against the US since we've been there. Not much of a win, but a win nonetheless.
No chewing required. It was a soft question. Those young men and women are the true 1%, and they volunteered. Sacrifices are made every day, by police, military, and civilians (like the young lady in Charlottesville, VA).
As long as those sacrifices are for the right cause, for the right reason, and to protect us here at home, then they are not wasted or sacrificed in vain.
As for your post's insinuation that I'm not satisfied that we're winning and it's my fault that land is being used in Arlington because of me and my supposed dissatisfaction, well, your wrong.
I was a combat medic. To this day, I wake up some nights with the smell and taste of iron in the room, with the feeling that my fingers are sticking together from the blood and tissue drying on them. I still have the blood soaked boots I wore. I have the uniforms with the stains and rips and holes. I have the pain in my knees from the mortar explosion and the loss of hearing from the battlefield. I visit Arlington once every few years. I visit some of the guys there that had my hands in their guts or chest or my fingers in their artery trying to slow the flow of death. I feel sometimes like I put some of those guys in Arlington because I didn't do enough, or that I made some sort of mistake that I still can't figure out, because I lost them, and I let them down.
So, again, your wrong. This is more than I should have written in open forum, but I thought that you may want to know where my perspective comes from, and it damn sure ain't in support of Trump, or in support of a war for the sake of war, or the loss of life just to maintain a war, or anything else you may have thought.
