First off, it seems as if you are unaware that President Obama HAS already significantly increased troop levels in Afghanistan since his arrival in office.
And I find fault with you claiming that 1. he is not listening to his military advisors, and 2. that you seem to somehow be aware of WHY he is not listening to them. I think both points are flawed and inaccurate.
I am just guessing, but methinks that you weren't around for Viet Nam when our president's military advisors promised him time after time that if only he'd send in MORE American troops, we could win the hearts and minds of the Vietnamese people... and then, six months later, they'd go in and ask for even MORE troops and promise the same result.
