I don't pretend to know how difficult it is to be the President of the United States. The man is looking tired and gray so I can safely assume a lot of the job is a pain in the butt.
And speaking of buts...... Sending in more troops whether for 18 months of 3 years will do NOTHING to destroy/weaken/demoralize or shame the Taliban.
How could anyone with access to supposedly sophisticated "intelligence" think that military might will lead to any productive end.
Oh wait, extending and increasing the deployments WILL be good for defense contractors, private soldiers of fortune, private special-ops units, all the manufacturers of special equipment as well as all the basics.
The military can't properly support and supply the troops there now. And where are they going to recruit 30,000 more people who are just as excited as punch to head off to one of the most challenging and scary operations that they could ever imagine?
There will always be terrorists. It's a matter of perspective. To some people, the United States is a terrorist regime. There will always be threats from some countries, from some groups, because we have not evolved into a wiser species by the year 2009, just a more technologically advanced consumer culture. There is still plenty of racism, bigotry, religious intolerance, gender bias, xenophobia and hate to monger.
Might in and of itself cannot make everything right. Because "right" is not universally defined the same by all.
Bring the troops home. Spend those billions on sorely needed domestic needs. A more enlightened foreign policy will do more to subdue radical threats than any military operation.
