What type of government does Syria have?

In theory: It is presidential republic, all executive powers rests with the president. The president can serve seven-year terms. Syria recently has just passed a new constitution that allows a term limit for the president to only be reelected once.
In reality: However, Syria is a Saddam Hussein-style sectarian presidential dictatorship. Opposition parties are banned and the parliament serves only as a rubber-stamp for the president's policies.
