I am very sorry about your son and as a brother grunt mourn him and those like him. But my family has served honorably and continuously since the civil war. So there is no reason to go there amigo.
You don’t seem to understand that taking on the mission of destroying ISIS involves getting involved in Syria. I am not sure why that is but it is. No nation building, no alliance with Assad but the destruction of ISIS on a daily basis primarily from the air. Of course we have to ally with some factions in Syria to gather Intel and have a presence on the ground. That is the real politik of the situation.
If you are unwilling to support that then you should just join Pat and advocate for fortress America and wait for the next attack in the lower 48.
I support destroying ISIS. Whatever that takes. Our mission is not to choose sides in Syria’s civil war, because ISIS is infiltrated on every front there.
