Is it time to bring our troops home ?

First let me say I support our troops 100 % But Ithink its time the US stops wasting American lives and billions of dollars to fight wars that are just too costly, taking too long, and all the billions of dollars we are spending in Iraq and Afghanistan should shofightingent fightiing terrorism in other ways. Plus, all these countries we are fighting in do not want us there. We were promised by Bshand Obama we woul be done with this war soon, plus, we have been training Iraquis to fght THEIR war, but after more than 5 years these people cannot defend themselves ?
