Yiddishkeit.Org posts these prophecies of note:
The Talmud, Yoma 10a, states: Rabbi Yochanan said in the name of Rabbi Yehuda in the name of Rabbi Ilai: In the time to come, Rome will fall at the hands of Persia.
The Yalkut Shimoni (midrash, compiled circa 500 c.e.) states: Rabbi Yitzchak said: The year that Melech HaMoshiach will be revealed, all the kings (leaders) of the nations will be struggling against each other. The leader of Persia will contest with a western leader and the western leader will go to Edom to get council from them.
The leader of Persia will respond and destroy the entire world. All the nations of the world will be trembling and shaking and falling on their faces. They will be seized by pains like labor pains.
The Jewish people will be trembling and quaking and saying: "Where can we go? Where can we go?" And [Moshiach] will say to them: my children, do not fear! Everything I did I did only for you! Why are you frightened? Don't be afraid--the days of your redemption have arrived!
Rabbi Yonasan Eibshetz, ztvk"l, (1690-1764) states in his sefer: Yaaros Dvash: At certain moment the time will come when Moshiach should have already arrived but the redemption has not yet come. The Moshiach will ask how it could be that the time for redemption has arrived and he still undergoes sufferings? The response that he will receive is that he must wait for nine months. Why? In order to wait for the fall of Persia at the hands of Edom, and then the final redemption will come.
This page from Yiddishkeit.Org led to some good investigation and learning by R. Nati and myself this evening. The Gemorrah and associated prophets have quite a lot to say about this, and G-d willing I'll write some of it up tomorrow.
For now, when reading the above, keep in mind (as I discuss in this post) that Edom refers to the West, or more specifically America. Persia refers to Iran.
Tying into the above, Rabbi Yess recently forwarded this article from WorldNetDaily...
Three carrier battle groups are converging on the Persian Gulf. The aircraft carrier USS Carl Vinson has departed Singapore and is currently crossing the Indian Ocean, en route to the Middle East. The aircraft carrier USS Theodore Roosevelt is also on the move, crossing the Atlantic Ocean, reportedly headed toward the Mediterranean.
Reports are also circulating that the U.S. Navy has dispatched ships containing nuclear armaments to reinforce the battle groups. This will be the first time since February 2004 that the U.S. has had three major carrier groups stationed on or around the Middle East...
