The illustration clearly shows the dial-in-power of the B61 being used to hit a military target next to a city with the city being unaffected. Just clarifying. I'm not in favor of these weapons or of war.
The media and sock puppet armies of the United States of Zionism have been trying to justify in the minds of the sheeple the use tactical nukes for a while now. They are 'Clean and Green'! Just have to set the dial correctly and that's all there is to it. American made nukes are humane and wonderful while Russian and Iranian nukes are bad bad WMD's.
Frankly, nukes of any type obsolete. Biological and psychological weapons are where it's at as far as legacy un-enhanced humans are concerned. I'm glad to be a relative mongrel genetically and ideologically speaking. Could be and advantage or a dis-advantage depending on how things play out.
