Came more out of bordom than needing to send a message, I love making these kinds of simplistic things.
A few things I learned a while back..
Of all the nations that have nuclear weapons, the USA has far more than anyone. Most of these countries have somewhere from 40-350 warheads. The two others are Russia weighing in at somewhere around 6000 while the USA has 8646, they alone probably have enough to scorch the entire earth.
The president is followed on international trips by a man carrying a 'foot ball' briefcase that lets him launch a nuke wherever he is. Knowing that I wouldn't feel very safe being in a place like Russia or China.
