War should be a last resort, and when implemented, should be so horrific it ends quickly.
*************
True that. When necessary, war should be intense retaliations of devastating punishment that is concluded as quickly as possible. The point being to convince an adversary that they should never provoke you again.
Case in point: I recently “invaded” and area inhabited by a small colony of wasps which provoked an immediate and intense defensive response by the insects. I will give them plenty of space in the future. :)
Iran is about the only country in the world I would fully support attacking. They are Shia. They believe the mhadi will appear when the world is in chaos.
They are working hard to build nukes. When they get enough, they intend to use them. Tel Aviv, New York, DC. Poof. They fully intend to use them.
