It is certainly true that this is the result of very intelligent hard work on the part of our outstanding military, and they should get the bulk of our gratitude. But, Obama has supported our efforts in terrorist wars pretty full heartedly, taking out Osama bin Laden, and now al Awlaki as well. Next up, I expect that bin Laden's number two, al Zawahiri, will be a headline before too much time passes.
Obama came into the presidency on promises of getting the U.S. out of Iraq and Afghanistan as soon as he could. He was contrasted to McCain who said he wouldn't leave until the job was finished. At the time of the campaign, I thought those two positions were very much the same, just worded differently. Once Obama took office and became debriefed on the actual situation in our war against the terrorists, he pretty much continued W's policies at home and abroad. Which I think just shows what any responsible president would have to do, given the realities of the threats he sees.
So, a very major defeat for the bad guys, and a success for our president. Congratulations!
