Well, this Iraq war has had about 15,000 deaths (including soldier suicides). We have about 2,000,000 members of armed forces. This number does not include the first Bush war in iraq, and partial occupation since then which include 10 years of over 500 US bombing runs on Iraq up to the 2003 invasion.
Do you mind the chances of you killing innocent civilians, or is this something to not ever consider?
Were not talking defending your home and family from a intruder, but going on adventures created by politicians, and funded by those same politicians stealing taxpayer money to pay for the bombs.
Perhaps the idea of destroying a family - who you were never threatened by or would even encounter - because of a politicians dealings with other politicians, is a non issue.
