I think Syria is the last country (after Libya and Iraq) in Muslim Arab world that describes itself "socialist".

The USA just continues the Cold War by eliminating all left-leaning regimes and all flavors of "socialism" however far it is from the kind of the USSR's.
Yugoslavia-Iraq-Libya-Sirya. Only Afghanistan was not somehow socialist when the USA invaded.

Any country that has oil industry, mineral resources under state control is in danger.
