I would spend every dime replacing the military equipment either damaged or destroyed in the past 6 years. That would be the biggest stimulus to the American economy.

Why? All of the money would be spent within the US, to US businesses, on goods manufactured in the US, all going to legal US workers, and thus the money would have the best chance of actually cycling within the US a few times.

People can complain about defense spending, but it always has been the best stimulus to local economies ever - and we get something for it. More taxes are generated through defense spendiing, so that other social programs can get funded without pain.

Sure, it sounds simple and many peacenik types will wring their hands and say making swords instead of plowshares is "not nice." However, we will need to replenish our defense systems, and it's a better deal than seeing all the money end up in China or elsewhere immediately on goods made elsewhere.
