When I see a soldier in the airport, I am not inclined to thank them for their service.
I am inclined to apologize for the fact that their lives have been co-opted by the government, their world view has been manipulated to serve its purposes, their lives have been put at great risk to enrich the corporations that benefit from their service abroad, and they are destined to be forgotten by the tax payers and left holding the bag of physical and mental atrocities once they are no longer useful.
Love the soldiers. But love them for being exploited beings just like you.
