Iran has on many occasions made it clear that the State of Israel should not and will not exist for much longer. They have supplied their proxies on Israel's borders, the Hamas and Hezbollah, with weapons and they now have a nuclear weapons programme that they will not give up.
We are currently in the midst of an increasingly heated psychological warfare campaign and disinformation effort of which it is impossible to make sense. However, it appears that Israel has failed in its attempts to prevent Iran from developing its nuclear capability.
Although, the idea of a nuclear Iran makes many very uncomfortable, the only country that is openly and aggressively being threatened by Iran is Israel.
There is some similarity to 1967, when Nasser moved his army into the Sinai, threw out the UN peacekeepers, closed the straits of Tiran and declared that finally Israel would be annihilated.
Should Israel go out on a pre-emptive strike?
