Not only is he a weakened leader, but I have read that there are some who say he is an apostate muslim. If that were true, this could be a credible threat.
In any case, it is a situation which is ripe for manipulation by those who are not friendly to this nation.
According to Islam, everyone is inherently a Muslim. There are no "converts," you simply revert to the faith you were born with.
On the other hand, everyone knows that Islam is passed down from the father, which would make Barack Obama a Muslim by default.
If he converted to Christianity-even the racist, bizarre, pseudo-Christianity of Rev'run Wrong-wouldn't that make him an apostate?
