Obama's newest war

Via Orbusmax, an interesting read about US and Turkish build up around Syria's boarders. Apparently we are orcastrating regime change there...but Sshhhhhh! dont tell anyone its the US behind it.

"The United States cannot be seen as being involved in regime change in Syria, but it is clear that Assad must go for the sake of regional stability," 


What is the difference between what Bush did with governments he didnt like and what Obama is doing now?
