Islam in general is a political cult aimed at world domination. Ahmadinejad is simply one of several people who sees himself as the leader of the jihad that will conquer the entire world (Osama is another), but he perhaps has more ability than other Muslim leaders to attempt it.
He’s been saying this “we will bury you” stuff for years, and I don’t think this instance of it is much more significant than any other.
What I do think would be a mistake, however, would be to think that inter-Muslim conflicts would prevent other Islamic states from joining him. Right now, Saudi Arabia may be a police state where Islam is imposed but an attempt is made to control it and keep the more radical elements from disturbing the equilibrium of the royal family. But I don’t think this would last very long if push came to shove, and I think the Saudi government would either turn aggressive or be overthrown and replaced with a jihadi leadership.
Mohammed was an Arab, the Arabs are always top dog in Islam because some of them are actually in Mohammed’s tribal/family line, and the Arabs are the “guardians” of the cult’s holy places, which happen to be in Saudi Arabia. Nothing can change this, not even Ahmadinejad. So eventually, we will end up having to fight the Saudis and their money and their oil, which enables them to pay or otherwise force Muslims all over the globe to attack us. Essentially, once it begins, we will be fighting all of Islam, including the Muslims in our own country. This is an aspect we must keep in mind.
And since we consider ourselves the "good guys", we have to allow them the first strike and retaliate, rather than decapitate the snake before it bites!
I'll repeat from prior posts: there have to be nuclear "accidents" at their fabrication facilities, some of which are hidden under their government headquarters (wink, wink).
Get the battle going BEFORE they are prepared to fight it. Scripture says that one third of the world's population will die in the final conflict; our job is to make sure that most of them are Muslim!
