In the case of Israel, I contend that the savings are there only in the sense that you “save” $200 if you go and buy a $1000 TV you don’t need that’s $200 off, but if you never bought the TV in the first place you’d be $800 better off.
Trump: Started 0 wars. Caused 0 economic crises. Bush: Started 2 wars (Iraq, Afghanistan). Caused the biggest financial crisis since the Great Depression.
