What is the reason, for a war against Iran ?

For spoiled-by-peace Westerners who have not suffered tyranny and war since a whole man-life, this may be appearing strange and unbelievable. But for those remebering historic lessons and being reminded of death and suffering in their own ranks time and again, it is expression of a knowledge that sometimes things for the better, or necessities, do not happen all by themselves, but must be fought for.

Wow what a pile of crap
For those remembering historic lessons most of the time the wars get fought for nonsense reasons, serve no real purpose and fail to achieve even a small measure of their stated desires.
