major nidal did the right thing. he correctly recognized US as the enemy of Muslims and that the enemy has to be struck where it hurts.

I disagree with your premise. He made a mistake to be in the US Army for sure. But he committed the act of a traitor. He had sworn an oath, and he broke that oath.
I am curious as to what you expect from Muslims in the US and UK. Genuinely.
