WhatsApp is already banned in Iran. It's difficult to see this as anything but another attempt by them to gain control over private communications involving their own people.
To me, the most interesting thing about this conflict is the side-choosing of the other nations, because that reveals what kind of games they're playing.
The article mentions the ban was lifted late last year:
"It banned WhatsApp and Google Play in 2022 during mass protests against the government over the death of a woman held by the country’s morality police. That ban was lifted late last year. ( https://apnews.com/article/iran-social-media-whatsapp-google... ) "
Russia and China totally expected, they don't help much. Except for Turkey NATO on Israel's side, not surprising. Iraq open sky used for airstrikes. Muslim 'allies' probably help refueling Israelis planes. The rest of the world doesn't care much.
