Hundreds of thousands joined rallies worldwide to back anti-government protesters in Iran. These protests face harsh and deadly repression. On Saturday, Reza Pahlavi, son of Iran's last shah, spoke to 200,000 people in Munich. He said he is ready to lead Iran to a “secular democratic future.” Pahlavi urged Iranians everywhere to keep protesting. He asked them to chant slogans from their homes and rooftops at 8pm (1630 GMT) on Saturday and Sunday. This was timed to match protests in Germany and other countries. Cities like Los Angeles, Washington, Toronto, Tel Aviv, Lisbon, Sydney, and London held similar rallies. Meanwhile, the US is preparing new talks with Iranian officials in Geneva next week. This is despite President Donald Trump saying a change of power in Tehran would be “the best thing.” Pahlavi, who lives in the US and has not returned to Iran since the 1979 revolution, told the crowd: “I am here to guarantee a transition to a secular democratic future.” He added, “I am committed to be the leader of transition for you so we can one day have the final opportunity to decide the fate of our country through a democratic, transparent process to the ballot box.” A protester named Said said, “The Iranian regime is a dead regime. It must be game over.” On Friday, President Trump sent a second US aircraft carrier to the Middle East to increase military pressure on Iran. He said a change of government in Iran would be “the best thing that could happen.” Earlier, Trump had warned he was “locked and loaded” to support Iranian protesters. More recently, US military threats have focused on Iran’s nuclear program. Last week, Iran and the US held talks in Oman about the nuclear program. A Swiss foreign ministry spokesperson said Oman will host more talks in Geneva next week but gave no details. Videos show Iranians chanting anti-government slogans despite crackdowns during the Islamic revolution anniversary. The US-based Human Rights Activists’ News Agency reports that at least 7,010 protesters died during the crackdown, with over 53,845 arrests. The actual numbers are likely higher. The Iranian opposition is split. Pahlavi faces criticism for supporting Israel and has never distanced himself from his father’s autocratic rule, which divides opposition groups.
