Well according to the front of my newspaper, it has something to do with the possible movement of US Marines into Yemen to hunt down Al Qidea cells in their back country- by invitation no less. Of course the rumored Al Qieda cells happen to be in areas that are not now and never have been under the control of the central government of Yemen- and in fact may be in Saudi Arabia since the Saudi/Yemeni border has in many areas never been surveyed or decided on.
But the current President of Yemen has decided that getting us to go in and bust heads for him in these areas- one of which is the home provence of the bin Laden clan- will only increas the power of his central government.
Also, he tried to do it himself two weeks ago and his best Army unit got its ass whipped severly. So he has come to us for help.
