As for the Iranian Fateh-110 and Zolfaghar missiles, which are capable of hitting targets at 300 and 700 kilometres respectively.
I believe this Iranian device, whose accuracy has yet to be proven (civilian GPS...?), does not solve the basic problem of Russia's weak ISR and command and control capabilities. Then the Russians will chisel at civilian targets again, in an attempt to weaken Ukrainian resistance. Hitting more civilian buildings with Iranian ballistic missiles, I believe, could raise the bar in a game where so far the Russians have only lost militarily. Indeed, in this case the quid pro quo could be ATACMS, which, unlike the Iranian cannonballs, are launched specifically at troop concentrations, depots, airbases, command and control centres... and Russian bridges, further damaging Russia's already disastrous ability to conduct a military campaign.
