I agree.
Every time there is negative news from Iran, Venezuela, Cuba, North Korea, or any other country which is opposed to US policy, many people (especially the far-right) claim these countries must be "unraveling". I think it is nothing but wishful thinking for the most part.
It was fully expected that there would be protests, and even violence, after the death of Grand Ayatollah Montazeri. It looks like the government was right.
And there still appears to be heavy popular support in Iran for the current rulers and their form of government, although that support is typically downplayed by US media.

It would be interesting to see the results of a truly unbiased poll to know how the people of Iran actually felt about all this. But those polls apparently do not exist. Instead, you have both sides generating propaganda to support their own movements.
