I dunno ... sharing frequently, never taking more than you give ... could be describing some kind of firefight ;)

That would be in contrast to the blessing, not the license.

If you are building a guided missle or the destroyer it launches from, you are doing so because you believe it to be good and not evil to have a strong military defense. And the best defense is a good offense or something like that, I don't really follow sports.

It wouldn't be in contrast to anything. Destroying a guided missile is probably an act of self defence, hence likely to be considered good by the author.

No. A "guided missile destroyer" is a type of ship that sends out guided missiles to hit targets, not the other way around.

It was not intended for the weapons system, which is a completely different beasts. There are many other things for a destroyer (which is a type of ship) to do. Good discussion here: http://www.reddit.com/r/programming/comments/1eyfk0/til_sqli....
