It`s mainly about destroying infrastructure. For the most part it will be done by pushing buttons. Peter, certainly the beginning of any modern war involves the pushing of buttons from afar. However, someone is going to be at the receiving end of some of those button pushers, and truups are going to be on the ground after those buttons are pushed. Infrastructure is not destroyed without a lot of people getting killed in the processxz. So please do not take the possibility of armed conflict with Iran so lightly.
