Is any means justified to ensure the survival of the nation?

That may depend on who you're fighting. Remember the movie "The Mouse That Roared"?

If you're fighting Canadians, I might say no, any means would not be right considering that the losers and winners won't be that far apart no matter whichaway the contest comes out.

But if you're talking the current crop of islamonazis, then yes, take off the gloves and do it to 'em till they don't get up no mo'.
