I am told by people I respect that Barack Obama cannot pull out of both Iraq and Afghanistan without becoming a one-term president. I think that may be true. The charges from various quarters would be toxic that he was weak, unpatriotic, sacrificing the sacrifices that have been made, betraying our dead, throwing away all former investments in lives and treasure. All that would indeed be brought against him, and he could have little defense in the quarters where such charges would originate.
These are the arguments that have kept us in losing efforts before. They are the ones that made presidents Kennedy, Johnson, and Nixon pass on to their successors in the presidency the draining and self-lacerating Vietnam War. They are the arguments that made President George W. Bush pass on two wars to his successor.
