Who Benefits From Lebanese Assasination?

I'm pleased to report that I'm not the only person who thinks Rumsfeld is capable of having Mr. Hariri assinated for political reasons, but one anonymous reader suggested that the Israelis are also suspects and this reader recommded that I read a UK journalist named Robert Fisk:

Administration officials have raised the pressure on Syria since President Bush's Inaugural Address and the Congressional testimony of Secretary of State Condoleezza Rice during her confirmation hearings, when she called Syria one of several "outposts of tyranny" in the world.

I wonder if the Bushites are deliberately forcing Syria and Iran to collaborate or if that's a side effect of their arrogant and short-sighted foreign policy in which they believe they can swagger and bully the world into compliance?
