The US spent more than 300 million per day during the GWOT for 20 years. We spent signifigantly more breaking our great enemy the USSR. We are breaking our current biggest threat to stability and still our longest enemy for pennies on the dollar comparatively every cent is well worth it. The 40 billion we have spent so far is just part of the trillion we spend every single year on the DoD. If u want the US to cut back demand our military make deep cuts to its budget.
