There is speculation that this "cultural sites" tweeting is to make the Elbonians spread their defensive resources out, so the real targets are less protected.
I suspect the “cultural sites” are memorials to Khomeini and the Iranian Revolution. Azadi Tower in Tehran comes to mind.
That, exactly, is the strategy. The Mullahs will try to protect their mosques rather than their radar sites.
Islamic terrorists hide their strategic weapons and arms under mosques. They’re probably building their nuke down there.
