From the Mother Jones article "And You Wonder Why We're Broke?" article by Michael Mechanic (here):
So we're rich. Does that really mean our military needs to be completely out of proportion with the rest of the world's armies? Would someone care to explain the logic on that? Because this is military imbalance.
To quote the soldier-scholar Andrew Bacevich from an interview I did with him in 2008: "Rather than becoming better at waging imperial wars, we need to move to a nonimperial foreign policy. That argument is not a moral argument—although you could make a moral argument—but a pragmatic one, that the prospect of more such wars is gonna bankrupt us."
