The background for this visit is interesting.  It is all about the 28 pages of the 9/11 report that reveal that Saudi officials funded the 9/11 terrorists.  A bill is in Congress that will allow 9/11 victims to sue Saudi Arabia over this.  Saudi Arabia has threatened to sell US securities if this bill passes.  Also we have to go back to Nixon and Kissinger when they created the Petrodollar deal with Saudi Arabia.  This deal saved the dollar after Nixon nixed the exchange of gold for dollars after De Gaulle about bankrupted us by exchanging his dollars for our gold.  We did not have enough gold to back all our dollars!  So Saudi Arabia can hold us at ransom.  Without the Petro Dollar the Euro could replace it as the world's leading reserve currency and our dollars would come home in plane loads causing hyperinflation like we have never seen.  You can bet your bottom dollar that Obama told the Saudis he will veto any bill that allows 9/11 victims to sue them.
