why russia and china will not allow un intervention in syria

 it not just that they were cold war allies.its not just that they are one of there best customers of military supplies.they have for nearly a year down played a simple fact.the people of the middle east are tired of being brutalized by there own leaders.they have instead replaced this truth with the cold war spin that the west is the cause.and another truth hides in their veto-they are scared an Arab spring might lead to a Russian and Chinese spring.this fact alone is why they are stonewalling the UN security council.and keeping it from doing its job,to protect the peace.
