Sending 30,000 more combat troops to Afghanistan will not make us any safer. Focusing a strategy around the central government in Kabul will not work, especially with a government as corrupt as the Karzai regime.
Sending more American combat troops into Afghanistan just means more of those troops will be doing more of the fighting instead of the Afghans themselves, who are more than willing to defend themselves as long as there are given the resources to do so.
I expected President Obama to be a little more hesitant before buying into the same failed strategies, however, I am disappointed because he has come up with nothing new or creative.
