Wars used to be paid for by raising taxes. Now we have no idea how much they cost. How many years in a row has the Pentagon failed it's audit? How many years (decades?) was the Iraq war funded through annual (unbudgeted) emergency measures? How many trillions in promised healthcare does America owe its veterans?
If the President had to make the case that taking on Iran would cost each American around $1000 on top of higher prices for fuel and food, how many would sign off on that?
So I guess I agree with Palantir. Be honest about the actual costs of war and chances are we will get into fewer.
