When will the regional Arab Gulf allies of the US buckle under the attacks by Iran?

Iran pursues a very clever strategy in response to the attacks by the US, retaliate against the Arab allies in the region.

Or will the attacked Arab allies (Saudi Arabia, Kuwait, Bachrain, Qatar) themselves finally resort to stronger military responses against Iran?

Seems to me this could be a matter of time and may happen sooner than later!

P.S. Where are the coward Europeans failing to help the US (e.g. with mine sweepers and escorting ships through the Strait of Hormuz etc.)?
