Mossad and the Israeli leadership is playing chess. Because Israel needs threats to survive.
manageable threats. threats that can be hyped up and blown out of proportion to assist the regime. If they didn't keep up a mentality of "hannibal at the gates" they would fall apart. So they manipulate affairs all around them - overthrow Assad, install ISIS - and keep the system going and the money and weapons flowing in. People talk about Russia having imperialist claims......but that is child's play in comparison. modern rabbinical judiasm insists that the jews as a group, and not necessarily any one person, will become the savior of the world, the messiah, and rule all the dumb sheep with a rod of iron.
