Two years ago both White Houses said that getting Osama was no longer important.
Six months ago they started continuously watching Osama in his house, which he hasn’t left for five years. No doubt they had surveillance on his electronic communications as well. Osama was marginalized to the point where he was reduced to babbling about global warming.
Last week, someone in Washington or Langley decided to score some political points by finally killing Osama. Suddenly Osama became an important military target again, and Obama a great military leader.
