I am pretty confident that overt support will appear soon if the zionist entity keeps seeking war because that is speeding up the material conditions that will allow that type of support.
Right now, I speculate that lots of Iran's allies are buying time to speed the development of their material conditions(BRICS, BRI, industrialization of the global south, diversification). A hot war will very likely affect these long term plans.
This was from last year. Sadly, I can not gauge how strong is this opposition now. It will be better if a knowledgeable comrade can fill in the gaps here.
