First, we don't really know where Osama is. He could be in a villa in Rawalpindi, protected by the Pak intelligence service, for all we know. But assuming he is in Waziristan...that's a huge area, and finding him and hitting him with a Hiroshima-sized bomb (which actually would require very precise targeting in those mts.) is not an easy feat. Then there's the little matter of having a nuclear-armed Muzzie nation with 150 million people falling into the hands of extremists when the present military govt. is shown to be unable to defend its turf against the U.S. infidels.
You have the same foolish idea about al Qaeda that the Clintons did: that it's a little criminal conspiracy which will die when its nominal head is killed, rather than an international organization with thousands of members and millions of petrodollars funding it. Even if al Qaeda were liquidated tomorrow, there is still Hezbollah, Hamas, etc. Italy hasn't been able to eliminate the much weaker Mafia in centuries of trying, despite imprisoning scores of its leaders.
What defeatist trash talk.
We start by killing as many as we can, and continue in the same way until it is done.
Your overconcern for the feelings of other nations is clintonesque in its short sightedness.
