[Adverblessly]

Bibi and a few other far right leaders are on record previously saying that Hamas is an asset, since it divides the Palestinians in Gaza from those in Yehuda and Shomron. In addition to that, it is my personal opinion that Bibi also considered them an asset for elections so that he has someone to oppose and can continually promise to "end Hamas" without ever actually doing it.

That said, if this was an intentional move by Bibi, it backfired severely since his support dropped drastically as a result of the attack (and how poorly he continues to handle it). I've heard there's quite a bit of internal opposition in his party in spite of the fact that most politicians there are just Bibi's bootlickers and that without him the party will likely lose a ton of votes.

Given that he is an incredibly gifted politician, it seems unlikely to me that he made the mistake of thinking that an attack will be good for him, so I find the conspiracy theory to be unlikely.

> as an excuse to raid Gaza

And to answer this one specifically, I don't think Bibi wanted an excuse to raid Gaza since it seems to me like what he wants most is just to continue the current status-quo where peace is impossible. It is possible that others in his current far-right extremist government were looking for such an excuse, but no chance that they would actually get to make that decision.
