In 2009, Iran was swept by demonstrations, just as it is now. But at that time, the protesters were shouting “Allahu akbar,” and there was no indication that they wanted anything but reform of the Islamic regime, not the end of the regime itself. This time, however, the protesters have been chanting: “We don’t want an Islamic Republic!” “Clerics shame on you, let go of our country!” Some have even chanted: “Reza Shah, bless your soul!”

What has changed? Donald Trump.

Reza Shah was the Shah of Iran from 1925 to 1941 and the father of Mohammed Reza Pahlavi, the Shah who was overthrown in the Islamic Revolution in 1979. Reza Shah admired Turkey’s Kemal Ataturk and set Iran on a similar path of Westernization and secularization. In chanting this, the protesters are emphasizing that they do not just want economic reforms, as has been the line of the establishment media in the West. Nor do they want an Islamic Republic that is less corrupt. They don’t want an Islamic Republic at all.

Now why would Trump have anything to do with this? Because he has been singular among the leaders of the world, and the Presidents of the United States since 1989, in demonstrating his readiness to stand up to violent intimidation. President Trump has already made it clear in so many ways, most notably by recognizing Jerusalem as Israel’s capital. Clinton, Bush, and Obama all spoke about Jerusalem being the capital of Israel, but backed off from recognizing the fact as official U.S. policy, for fear that Muslims would riot and kill innocent people, and that such a recognition would jeopardize the chimerical and fruitless “peace process.”

So should terrorists decide where our embassy should be? Trump was not willing to concede this point. And when one man shows that bullies can be confronted and stood down by people with courage, others are inspired to make the same kind of stand. This new Iranian uprising came just weeks after Trump’s Jerusalem announcement, after the threatened rage and riots of Muslims worldwide in response to that announcement proved to be largely a fizzle.
