You could take care of a lot of sick people and provide a lot of unemployment compensation with the money the US government spends on maintaining and expanding its empire. From Scott Horton at antiwar.com:
Can anyone think what our society might have spent six and a half trillion dollars on instead of 20 years of war in the Middle East for nothing? How about the trillion dollars per year we keep spending on the military on top of that?
Invading, dominating and remaking the Arab world to serve the interests of the American empire and the state of Greater Israel sounds downright quaint at this point. Iraq War II, as Senator Bernie Sanders said in the debate a few weeks ago, while letting Joe Biden, one of its primary proponents, off the hook for it, was “a long time ago.” Actually, Senator, we still have troops there fighting Iraq War III 1/2 against what’s left of the ISIS insurgency, and our current government continues to threaten the launch of Iraq War IV against the very parties we fought the last two wars for. This would almost certainlythen lead to war with Iran.
The U.S.A. still has soldiers, marines and CIA spies in Syria, Afghanistan, Somalia, Libya, Mali, Tunisia, Niger, Nigeria, Chad and only God and Nick Turse know where else.
