If this report here ever came to pass, then the full logic of war escalation in Afghanistan, a la Vietnam, is in place.
With more troops sent, there will be pressure to send even more when the goings get tough. The military will predictably ask for even more to get the job "done".
Withdrawal in the face of more casualties will be tagged by the Hawks back home as "traitorous" and "cowardly".
Obama, like LBJ, will then be forced to escalate more. Dollar would go way down, gold way up. This would be a rerun of a bad and familiar movie with a predictable and disastrous ending. Watch this space.
