Tehran Bureau has an enlightening piece on the politics of the coup:
[One goal of the coup] is to start preparations for the eventual successor to Ayatollah Khamenei. He is known to be ill. By accusing Mr. Rafsanjani of corruption, the second-generation revolutionaries wish to eliminate him — the head of the Assembly of Experts appoints the Supreme Leader — as the natural successor of Ayatollah Khamenei, hence paving the way for Ayatollah Mesbah Yazdi who is a member of the [Assembly of Experts]. Everything appeared to have been planned well in advance, but the coup leaders did not expect the people to stand up to them.
This is a pivotal moment in Iran’s history. If the reformists and the Iranian people cannot reverse the outcome of Iran’s rigged elections, Iran will enter a dark period of dictatorship, with no light at the end of the tunnel. The country will be controlled completely by the military/security forces, with an unelected Supreme Leader as its titular head, and no elections (or extremely meaningless ones). This would be a terrible development for the rest of the world as well.
