You are delusional my friend, at its best.So while I leave you there,let me assure you,Israel,without its nuclear weapons is practically nothing.It's a very tiny country and its infrastructures can be destroyed in no more than a day.
And about the so called free nation thing, you are wrong.Israel is built on lands that belongs to someone else.Besides,political system has nothing to do with being able to win a war.Also,we are not interested in any war.I think it's your PM, who is threatening that we will attack this day/that day and has made a clown out of himself really.There is a reason you don't attack Iran,and that isn't your super-strong army I suppose.It's simply because you can't win the war. Spare me for the terrorist part,because the only thing that comes to mind by hearing the name Israel,is killing women,children,terrorizing civilians and at last,racism.
About the importance part, it doesn't take a genius to understand that Iran is located in of the most geostrategically important places in the world and it's not just for gas or oil.It's human resources,geography,natural reserves,ideology,all together make it an important country.Why would Russia turn to Iran for oil or gas,while it has the biggest reserves itself?regarding China,it's just business as usual.Also all of these countries have somethings in common:countering western influence in Asia and the world is the most important one.
Regarding Israel's insignificant gas reserves,well you can use it for yourself, but you can't use it as a weapon against any country.Don't you overestimate your power in this matter.
