Easier said than done. Let's look at things from a rational/neutral perspective(/that's what i always try to do when making an observation geopolitically). Let's face it. Arab states led by KSA consider/view Iran (rightly so i must say, I'm looking at things from their perspective) as a far bigger threat to them than Israel. Israel doesn't pose any threat to Arab states/governments. The only issue is between Israel and Palestine. So Arab states don't feel any threat coming from Israel per se. Contrary to Iran post Islamic revolution. So Arab states will obviously focused on their bigger threat. That's realpolitik and normal.
Noticed that prior to the Islamic revolution which was taken over by the Mullahs, Arab countries where more focused on Israel and the Palestinian issue, since they didn't face any threats from Iran back then(if anything they had very cordial/friendly ties with the Shah/Iran) or any other major state per se. So they could focus more on the Israel Palestinian issues. Hence the several battles/conflicts they fought against Israel.
Ironically, the Islamic revolution in Iran had the unintended consequence of being the best thing Israel could actually ask for, since it helped redirect Arab states priority away from Israel to Iran who emerged as their biggest threat and the Mullahs openly express their will/intention to export their version of Islam/revolution to the entire region/Arab world to 'liberate' the Arab people from their 'despotic government/rulers' and establish their form/version of revolution. This is what helped reshaped the entire Middle East and led to the current Arab-Iranian split and geopolitical conflicts/sectarian conflict and competing interests that spread to the region to this day. Israel/Palestinian issue was then kept on the backburner. this is how we all got here.
So yes, there will be condemnation from both Arab states led by the Saudis and from Iran and the others, but that's it, nothing much, both sides are focused on each other and know the bigger picture is about their competing interests in the entire region. Israel is just a slide show to this.
