soldiers @ the dallas/fort worth airport

while i was travelling to Chicago recently, i had a lay-over in Dallas. I was sharing the airport lounge with a sea of soldiers, all deploying to iraq. I spoke to many of them, asking them if they were returning there or first timers. What struck me most was their youth. Of course I am aware of what is happening overseas, but only as an outside observer--and only armed with what the media is filtering through to us. these kids made it even more real & sad & they even felt it was futile...
the death toll is approaching 2400 for our guys, and countless deaths for the Iraqi civilians.
when i say countless, i know there are some spotters saying in the tens of thousands.
anyway, no matter my take on the war, i was moved to tears to see all these scared young kids on their way to the unknown. There were many people there in the airport just saying goodbye & going up and down the line hugging strangers, i imagine they had lost children or family members. a very moving and sad scene, and i was there in the safety of the airport, only going to Chicago not Baghdad. what can we do?
