The alliance between Iran and Al Qaeda is reminiscent of he alliance between Hitler and Stalin. To thrive Stalin had to ignore the manner Hitler treated not only Socialists but also Communists in Germany and elsewhere. Iran is doing the same. In Pakistan (see also) and Iraq , AL Qaeda is murdering Shia whereever they can find them, denounces them infidels and Iran continues the alliance BECAUSE now and then the hatred they share for the Jews and the West is greater than their care for their fellow coreligionists.

See, Tehran Accuses Israel after FBI Catches Iranian Surveillance Teams Red-handed:

US intelligence experts are certain that data gathered for Tehran by the captured Iranian surveillance team may well have reached al Qaeda, some of it passed deliberately. Osama bin Laden’s organization is believed to be plotting a major attack in the United States. The Islamic Republic is in the habit of using proxies for its terror campaigns, like the Lebanese Hizballah against Israeli targets. That Al Qaeda operatives are harbored in Iran and run cells in many countries make it a natural partner-in-terror.

In the wake of the round-up of Iranian teams, al Qaeda cells were also picked up in Brussels, Amsterdam, Madrid and the Uruguayan capital of Montevideo. Hizballah surveillance teams were rounded up in parts of West Europe.

The US interrogation of the Iranian surveillance team and sightings of other watchers have led Israeli intelligence and security chiefs to conclude that Tehran was plotting simultaneous terrorist strikes across America and other parts of the world, blowing up Israeli missions and Jewish centers and taking hostages in several places at once. The captured team may even have been feeding deeply buried terrorist cells set up to carry out this string of assaults and still at large.

Israel has accordingly put all its embassies, consulates and other missions, as well as airlines, shipping companies and overseas company offices on high terror alert. Security has also been stepped up at overseas Jewish institutions and schools.
