From Zero Hedge:

In a shocking development, Saudi press Al Mayadeen reported late on Saturday that prominent billionaire, member of the royal Saudi family, and one of the biggest shareholders of Citi, News Corp. and Twitter – not to mention frequent CNBC guest – Al-Waleed bin Talal, along with ten senior princes, and some 38 ministers, has been arrested for corruption and money laundering charges on orders from the new anti-corruption committee headed by Crown Prince Mohammed bin Salman, while Royal princes’ private planes have been grounded…

Bin Talal’s arrest and the government reshuffle caps off a bizarre day for Saudi newsflow, which started with the resignation of Palestinian prime minister Saad al-Hariri, who announced he was quitting due to fears of an assassination plot, allegedly organized by Iran, followed shortly after by the Saudi defense forces intercepting a ballistic missile as it was about to strike the capital Riyadh.

From Moon of Alabama:

Four days ago we asked: Is The “Moderate Al-Qaeda” Set To Target Hizbullah?. The implied answer in that piece was “Yes, the war is coming to Lebanon.”

Today the Lebanese Prime Minister Saad Al-Hariri resigned with a statement issues from Saudi Arabia on the Saudi Arabian TV station Al Arabia (video). This is the opening shot of the war.

The Saudi-Israeli-U.S. axis will lose this war while Iran and Russia will win from it…

The resignation of Hariri is intended to provoke a constitutional crisis in Lebanon and to prevent new parliament elections. The further Saudi plan is likely to evolve around these elements:

• The Trump administration will announce new sanctions against Hizbullah and against Lebanon in general.
• The Saudi government will slip some of its al-Qaeda/ISIS proxy fighters from Syria and Iraq into Lebanon (possibly via Turkey by sea). It will finance local Lebanese terror operations.
• There will be new assassination attempts, terror attacks and general rioting by Sunni extremist elements against Christians and Shia in Lebanon.
• The U.S. will try to press the Lebanese army into a war against Hizbullah.
• Israel will try to provoke and divert Hizbullah’s attention by new shenanigans at the Lebanese and Syrian border. It will NOT start a war…

In their manic attempts to push back against perceived Iranian (and Russian) influence the Saudis and the U.S. have enabled Iran (and Russia) to gain better and more secure standing that they could ever have hoped to achieve otherwise. Why the Saudis think that their new adventure in Lebanon will have a different result is beyond me.

From the comments:

The main desire for change in Lebanon is the Israeli desire to be rid of Hizbullah and its missiles.
