Steve you are right the Iranians have never said that they will use nukes against Israel. That still doesnt let me rest any easier because they have threatened the west and Israel with complete destruction and they are attempting to build nukes. Add to that a fanatical religious government. The threat is implicide Im sure we all agree.
As iron rod has said we should all be able to rest easily in our beds tonight thanks steve.
The truth is steve we can sustain conventional warfair but atomic warfare is a luxury the world cant afford.
