Is Ayatollah Mojtaba Khamenei in charge after all?

Despite facial disfigurements and other injuries to his body and his hideaway never-seen existence, Ayatollah Mojtaba Khamenei who took over as Iran's supreme leader when his father was killed on the first day of the US/Israel war with Iran, seems actually to be in charge and making decisions which others are obeying. He seems to have taken the hardest-possible line on doing any sort of deal with the US and appears determined to put his stamp on the future of Iran. While the military in the shape of the commanders of the Islamic Revolutionary Guard Corps, are the visible leaders of the country, the disabled supreme leader is still issuing orders. How it is being done is difficult to guage but clearly the courier system he is suspected of using from his command bunker is working effectively. Mojtaba, I am sure, has one driving motivation for taking the toughest line with the US. He blames Trump and Benjamin Netanyahu, the Israeli prime minister, for the assassination of his father, the late Ayatollah Ali Khamenei. He no doubt wants revenge and the best way, I giess, is for him to put so much pressure on Trump by hanging on to the Strait of Hormuz, that the US will just give up. Whatever happens in the next few weeks, Iran's control of the strait is not going to be conceded in any future deal, if there is ever a deal. Mojtaba may have vanished into his bunker somewhere, but he is alive and dictating the terms for what he will see as Trump's surrender.
