Do you have any stats to show that only America has a welfare system that is abused? Last I checked quite a few countries in the west have some sort of welfare. Do you really want to be apart of a country that does not have a welfare system where if "a person gets their leg blown off" they have to fend for themselves? I mean that's possible but I doubt you hold countries like Somalia, Yemen and Syria in high regard.
You are not wrong though, enlisting is a choice. I just find it interesting how your statements above remind me of the scene in Rambo when Stallone said "Who are they to protest me? Who are they unless they have been me and been there and know what the hell they are yelling about." "In the field they had a code of honor. I watch your back you watch ours. Back here there is nothing." "Back there I could fly a gunship. I could drive a tank. I was in charge of multimillion dollar equipment. Back here I can't even hold a job parking cars."
I just find it amazing how much empathy has been lost in the past few years.
