Total cost including interest is estimated to be over $5T, over 7000 casualties and over 30000 wounded American soldiers. Despite this great expenditure, terrorism is on the rise. So I have to ask, did this line of thinking make the problem better or worse?
I don't know what the answers are, but I am glad I was born here and not in Goatfuckistan. I have empathy for the non-terrorist refugees which far outnumber the terrorists.
