I wonder if this attack was sponsored by Saudi Arabia.
"As-Safir said Prince Bandar pledged to safeguard Russia’s naval base in Syria if the Assad regime is toppled, but he also hinted at Chechen terrorist attacks on Russia’s Winter Olympics in Sochi if there is no accord. “I can give you a guarantee to protect the Winter Olympics next year. The Chechen groups that threaten the security of the games are controlled by us,” he allegedly said. "
“We understand Russia’s great interest in the oil and gas in the Mediterranean from Israel to Cyprus. And we understand the importance of the Russian gas pipeline to Europe. We are not interested in competing with that. We can cooperate in this area,” he said, purporting to speak with the full backing of the US. "
So they are using terrorism as a form of corporate blackmail.
I wonder if the US will still protect them when their oil runs out in another 10 or so years? They are already spending more than they have.
Eh maybe but it's not like there haven't been bombings from groups inside of Russia for awhile now.
These groups probably are getting help from Saudi interests but I doubt they are calling the shots.
