Death of a Terrorist: Who Carried Out the Assassination and What are the Consequences?

Many experts say that only Israel's Mossad (legendary secret service) had sufficient intelligence and expertise to carry this out - Israel is denying involvement on one hand while bracing for horrific responses.
