Whatever whoever is saying...there is no justification for attacking another country on the mere suspicion that it might one day attack you.

There is also no justification for saying, "Well, we had to do it, you see, because they're insane..."

That sounds to me like the kind of feeble BS excuse that someone like Hitler or Goebbels would come up with for invading another country. Only the person who utters the excuse himself can be blind to the innate hypocrisy of taking such a position to justify his own premeditated act of murder.
