So you don’t dispute this reporting, don’t dispute that this was Musk’s idea, which implies he lied about it immediately afterwards.

And just so i am clear on your philosophy there is no guilt that rides whatsoever with presenting this capability to the leader of the free world who then goes and does exactly what you suggested resulting in many people dying while a nation fights for its life.

If he really did give Trump the idea, do you see Musk as having no responsibility whatsoever?

Trump is an idiot and does what the last person told him. When you interact with such a person, you can't wash your hands and say "I just advised, I have no blame".
