If WW3 breaks out because of Israel, will the non-NATO countries be able to bring NATO countries down to their knees?

NATO = 32 countries + Israel. 4 nuclear countries (USA, UK, France, Israel).

Non-NATO = more than 100 countries. 5 nuclear countries (Russia, China, India, Pakistan, North Korea).


It is not black and white that if WW3 breaks out then every single country on either side will jump in guns blazing. A lot of countries will avoid getting involved or even being at the frontlines. A lot of countries will fight proxy and avoid breaching the various treaties they have with countries on the opposite side. A lot of countries will play defense rather than offense.

With all things considered and hypothetically speaking, if the outcome has to be surrender of one side, will the non-NATO countries be able to defeat NATO countries?
