"We"? How many of those wars were started by popular demand, with protests on the streets demanding our leaders take military action? "We" are being blamed for the actions of oil and weapons lobbyists (whose wars are paid by our taxes), and then asked to face the consequences of the actions due to their subversion of democracy.
We pay for the wars we don't want, we get the blame, we get to deal with the immigrants, and in the end, we still have to pay for the oil - the oil companies that benefit (always unnamed) don't hand it out for free!
