Ahmedinejad = Kedorla'omer?
In the past, I've compared the current president of Iran with Haman Harasha. The reasons for making such comparisons are too many to enumerate.
A more obscure comparison, but one that might also be utilized, is a comparison to Kedorla'omer. Kedorla'omer was the king of Elam, which was located in modern-day Iran. He was one of the 4 kings that Avraham fought to rescue Lot.
The Tanhuma says:
Shem knew how dangerous Elam was and didn't seem to care that his first-born was killed. (This Midrash implies that Kedorla'omer was synonymous with Elam himself. Also, see how the Torah Sheleima quotes the Midrash.) Not only didn't he care, but he gave Avraham presents for doing so. The rest of the world - even the Arab world - is doing all it can to get Israel to fight against Iran.
Notice from the Midrash quoted above how Elam=Kedorla'omer has 3 sons. Wikipedia says Ahmedinejad ימ"ש has 2 sons and a daughter.
Using the Ashkenazic usage of Hebrew transliteration:
אחמעדינעדזשאד = 569
כדרלעומר = 570
But putting all that aside, we know that the first leader of the 4 kings was Amrafel, the King of Shin'ar. Shin'ar is Bavel and Amrafel is Nimrod. Nimrod started the whole war just to get to Avraham. But Nimrod/Amrafel later became secondary to Kedorla'omer, who took over the reigns as leader. The Midrash explains this as "בעל קורה טעין בעוביה" (the owner of the beam carries the thick part).
Similarly, Babylonia and its leader Nevuchadzetzar was the leader of nations against the Jewish people until they were defeated by the Persians.
Similarly, Saddam Hussein ימ"ש was the leader of nations against the Jewish people 20 years ago until he was defeated twice by the U.S. Now, Iran has taken over as our biggest nemesis.
We know that the 4 kings are compared to the 4 kingdoms into which we were exiled. Just as the 4 kings were defeated by Avraham Avinu, the 4 kingdoms will be defeated by Mashiah. מעשה אבות סימן לבנים. When it says (while Avraham was winning the war against the 4 kings) "ויחלק עליהם לילה", half of the night was for Yetzi'at Mitzrayim, while the other half was for the future redemption. May that day come speedily in our days. Amen.
