Here is a link to an excellent article written by Robert Gates. It intelligently examines our current commitments and capabilities as well as looking towards the future.

I realize it will be an effort for some to read but please I ask you to do so.

Gates as most of you know was appointed by Bush and has agreed to stay on under Obama for the time being.

What does Gates say? Here is an exert from the conclusion of the article.

"I have learned many things in my 42 years of service in the national security arena. Two of the most important are an appreciation of limits and a sense of humility. The United States is the strongest and greatest nation on earth, but there are still limits on what it can do. The power and global reach of its military have been an indispensable contributor to world peace and must remain so. But not every outrage, every act of aggression, or every crisis can or should elicit a U.S. military response.

We should be modest about what military force can accomplish and what technology can accomplish. The advances in precision, sensor, information, and satellite technologies have led to extraordinary gains in what the U.S. military can do. The Taliban were dispatched within three months; Saddam's regime was toppled in three weeks. A button can be pushed in Nevada, and seconds later a pickup truck will explode in Mosul. A bomb dropped from the sky can destroy a targeted house while leaving the one next to it intact.

But no one should ever neglect the psychological, cultural, political, and human dimensions of warfare. War is inevitably tragic, inefficient, and uncertain, and it is important to be skeptical of systems analyses, computer models, game theories, or doctrines that suggest otherwise. We should look askance at idealistic, triumphalist, or ethnocentric notions of future conflict that aspire to transcend the immutable principles and ugly realities of war, that imagine it is possible to cow, shock, or awe an enemy into submission, instead of tracking enemies down hilltop by hilltop, house by house, block by bloody block. As General William Tecumseh Sherman said, "Every attempt to make war easy and safe will result in humiliation and disaster."
