YMMV.

The standard doesn't say anything to prohibit such a consequence, but in
real life such an outcome is possible only if your program is executing
in an environment that allows it to send out launch messages to real
missiles.  In such a context, a program that was intended to launch a
missile strike, and seemed to do so, but actually failed to do so, would
arguably be worse.  If the enemy knows that you are running such
defective software, that enemy might not be deterred from attacking.
