The answer is obvious and we have not only this Neo-Commie Despot (Barack Hussein Obama) to blame, but also our very own "Compassionate Conservative" clueless, RINO, Boosh, who allowed both Iraq and Af-Gan to form new Constitutions with Islam (Sharia) being the controlling authorities.
That in itself was to be the deciding factor in neither country ever being a true ally; their never being willing to engage fellow Islamofascist terrorist brethren; and the guarantee that what ol George was so gun ho about (Nation Building and Hearts and Minds) would never come to fruition, never mind, that the people in those countries would never experience freedom, rights and liberties.
BRING EM' ALL HOME and bring them home NOW!!!
Well, that will sure answer the "was it worth it?" question, won't it? And the answer will be "NO", never mind that they started it by killing 3000 of our people out of a clear blue sky -- and we are going to let them finish it? And give them bragging rights?
Suggest you rethink a bit, amigo.
