Missile countries need some random events to help spice up the game. I suggest a small chance of an accidental missile detonation, which causes 1 random nuclear, chemical, or cruise missile to explode and do a small amount of its respective damage (probably less than an equivalent missile attack from an enemy country). The positive event would be 3x missiles produced in a turn.

TRIPLE MISSILE FTW...err that would be crazy...*maybe* 3x the probability of producing 1 missile ;p

Random missile explosions seems amusing tho haha

and logical! the more missile you have the higher the chance of you getting into an accident! nice one, and probably you can have SDI/Military tech to lower the chance of accident

ive gotten tripple missle a few times actually... Same with doubles... it was lovely.
