No one is talking about this and it seems the most plausible to me =

Russia supplied Hamas with weapons and supplies it had captured early in the Ukraine conflict, earlier this year. This was reported by several news facilities at the time.

Now suddenly Israel is attacked out of the blue by Hamas, at a critical time of Ukraine's offensive to retake lost territory.

I think it is highly likely that Russia is behind the attack on Israel. This is a perfect tactic to derail/divert support that was going to Ukraine. I mean just look at all the support that has been pledged within a day. Support from all the same countries that were vowing support for Ukraine.

Do the math!
