Other countries are not volunteering to help prosecute more attacks on Iran, because they are already victims of those attacks, and it's bad enough that the USA and israel aren't even apologizing for hurting them, much less paying for the damages.
Thus, the offer to "help patrol the strait" once the USA and israel stop attacking is meant to persuade the USA and israel to stop attacking, not an indication of support for the USA and israel's attacks. Indeed, most countries do not support the USA and israel's attacks on Iran, were totally okay with the status quo, and would have preferred if the USA and israel had not attacked Iran.
