Volgograd used to be called Stalingrad. There, between August 1942 and February 1943, a critical battle was fought between the invading Germans and the Soviet Union. The heavy losses inflicted on the German Wehrmacht make it arguably the most strategically decisive battle of World War II. The Battle of Stalingrad was a turning point in the European theatre of the war. 
On December 29, 2013, at the Volgograd-1 railway station, a suicide bomber killed at least 18 people and injured many more. The next day, December 30, 2013, another suicide bombing targeted a trolleybus in Volgograd. Sixteen people were killed and many more were injured. 
Emerging news points to Saudi Arabia as the hidden culprit behind these vicious Volgograd attacks. Robert Parry, an American investigative journalist best known for his role in covering the Iran-Contra affair for the Associated Press and Newsweek, reports as of December 31, 2013 that a “diplomatic leak” reveals that Saudi Arabia’s intelligence chief Prince Bandar bin Sultan made a veiled threat to Russian President Vladimir Putin at a meeting on July 31, 2013. At the time of the Prince Bandar meeting with President Putin in Moscow, pressure was intensifying for Western intervention in Syria. Bandar allegedly offered Putin “protection”, in the manner of a gangster running a protection racket. Reportedly, Putin was given an “offer he can’t refuse”: If Putin would abandon Syria to the planned Western onslaught, then Saudi Arabia would restrain its Chechen terrorist clients who have been attacking Russian targets for years. 
Putin reportedly grew furious, interpreting Bandar’s offer as a warning that the upcoming Sochi Winter Olympics would be threatened by terrorism if Putin didn’t comply. 
Refusing to yield to implied threats, Vladimir Putin and Russia stayed loyal to the legitimate government of Syrian President Dr. Bashar al-Assad. In late August of 2013, when the U.S. Congress was not in session, a massive launch of U.S. missiles against the sovereign nation of Syria was narrowly averted. Russia played a crucial role in easing sudden tensions and negotiating elimination of Syria’s chemical weapons. But this almost miraculous outbreak of peace ran contrary to Saudi plans to overthrow the Assad government in Syria.
It was payback time! The Saudis had not been given “respect” by Vladimir Putin. It was like the Rodney Dangerfield routine, “I don’t get no respect”, which the late Mr. Dangerfield had invented after listening to the conversations of mobsters between acts of his comedy monologues. Like the crafty Don Corleone, Prince Bandar bin Sultan stroked the purring cat on his lap and bided his time.
If you follow the RT.com website or watch their news reports via video streaming, you know that the Russians dearly love their upcoming Sochi Olympics. To them, it is like movie producer Jack Woltz’s beloved horse, “Khartoum”, in the movie The Godfather. We all know how the crafty Don Corleone handled the situation when Woltz wouldn’t include singer Johnny Fontane (Frank Sinatra) in his upcoming movie (From Here To Eternity)… You know, “What is that horse’s head doing in my bed, and where is the rest of him?” In the case of Vladimir Putin, the “horse” was the Sochi games and the “head” was the Volgograd bombings, which have cast doubt on security for the anticipated Winter Olympics and possibly undermines their success.
