To accomplish this Israel has relied on it's "relationship" with America and the EU and has also used the tragic history of the Jews whenver they could (After all, what good is a thing if you can't use it?) In this case it means that, if America won't start a war with Iran, then Israel will start a war with Iran which America would then join very quickly, allowing Israel to retire to the sidelines. It is certain that America has warned Israel not to do such a thing, but Netanyahu has ignored Obama before and avoided any consequences. It is likely that Netanyahu believes that if Israel starts the war that America must join no matter if Obama wants to or not. Could it be that Netanyahu thinks that he can make policy for America which America must follow?
