That's just simplistic western propaganda. Sporadic protests, nationwide or otherwise, don't mean anything unless they are backed by long-term-opposition with strong grass-roots and singular political goals. Iran's regime remains strong and stable - it controls all the political institutions, it controls the civilian government at the local level, it controls the religious / cultural institutions, it controls the military and it has substantial support from the people. Why do you think Israel or the US isn't sending boots to the ground? Apart from the official military, the IRGC has a voluntary civil force, that can be armed by the Iranian military, in every district - if Israel or US send their soldiers to Iran, they will face a very brutal urban warfare with a high death toll.
