With the Shia majority in Iraq now running the country, the Arabs now have to confront Iran directly. And that they are doing. Saudi Arabia is supporting the Palestinian Fatah organization against the Iranian supported Hamas. Saudi Arabia is also using its money to support Sunni Arab, and Christian, factions in Lebanon, against Hizbollah, the Shia minority and its Iranian backers. Saudi Arabia is also giving support to the Sunni Arab majority in Syria. For decades, the Saudis tolerated the Shia minority that ran Syria. No more. The situation has changed, especially with Iran gaining speed in its effort to build nuclear weapons.
The Saudis are even, secretly, cooperating with the Israelis. Iran has always been seen as a greater danger to Israel than the surrounding Sunni Arab nations. Hizbollah, which is a Lebanese Shia organization, made a name for itself during its disastrous attack on Israel last Summer. Although Hizbollah lost by every measure, they won in the arena of public opinion. Both the Israelis and Saudi Arabs (and Sunni Arabs in general) hated that. . . . The Saudis are committing over $100 billion to this battle, and doing it out of the purest of motives; self interest.
Interesting.
