They imply that nato is arming and equipping Israel

Yes industry standard oppose NATO because of russia but didn't mention the form of backing

So, many countries support the genocide. It’s not “nato” only

But this post is about nato and israel not russia . You are simply, doing whataboutism. Now if there is an article about china supporting Palestinians mentioning it's good relation with Israel it is fair because it is iexposing hypocrisy rather than whataboutism

Why not say UN supports the genocide?

Because the Un is multiple entities with different functions none support Israel while nato is a military alliance . Where did the UN approve genocide and israeli military actions?

Saying shared training and exercises is “backing” is just as silly as people getting upset that China was doing military excericises with Russia.

No it is not silly
