I'm learning farsi myself...nuclear war in the mid east is ungood for everybody. Modern nuclear weapons can be "detuned" from about 300 ktn down to about 1/2 ktn. For comparison Hiroshima 10-15 ktn depending on the source of data. All a matter of how well you master the technology..if you have the time and the inclination to fight a "limited" nuclear exchange. Otherwise, bigger bombs make bigger body counts.
