Seriously 'merica...is that your answer to everything?
"oh look, the japs crushed 90% of our naval forces, lets send some nukes"
"oh no, you have nukes, and so do we, get rid of your nukes, lets have a 9 year war..."
"oh no, there is a comet coming towards the world, lets send bruce willis and some nukes...problem sorted"
but anyway, I dont have a better idea. The Ruskies are fairly good with that stuff too...guess you got to weigh up the effects of a nuke over the effects of oil spilling the fuck everywhere. Maybe a "big but not so isotonic" bomb might be the go?
