Some “warning“…:

Saudi Arabia’s King Abdullah has warned Vice President Dick Cheney that Saudi Arabia would back the Sunnis if the United States pulls out of Iraq, according to a senior American official.

The official said the king “read the riot act” to the vice president when the two met last month in the Saudi capital, Riyadh.

The New York Times first reported the conversation Wednesday, saying Saudi support would include financial backing for minority Sunnis in the event of a civil war between them and Iraq’s Shiite majority.

Honestly, who expected them to NOT get involved?  The US goes in & somehow makes the region worse than usual, it’s going to pull in some neighbors.  That proposal by the Iraq Study Group to get Iran involved is gonna prove unnecessary if this does happen, because they’ll jump in anyway — though obviously not for the goal that they intended.
Eh, other 80’s things are making a comeback, no surprise that proxy war might join ‘em.
