On Saturday, demonstrators opposing the Iranian regime took to the streets in cities worldwide, advocating for a shift in leadership during what was called the Global Day of Action Rally.

In Munich, Germany, the protest coincided with the Munich Security Conference, drawing over 250,000 participants.

According to a press release issued by Munich Police, “This event marks one of the most substantial rallies in Munich’s recent history, with a notable peacefulness prevailing despite the large attendance.”

The demonstrators were heard chanting slogans like “change, change, regime change” and “democracy for Iran,” as they waved green, white, and red flags emblazoned with lion and sun emblems. A few attendees also sported red hats bearing the slogan “Make Iran Great Again.”

Among the massive crowd was exiled Iranian crown prince Reza Pahlavi. Speaking to Reuters, he suggested that any potential attack on Iran might either weaken the regime or hasten its downfall.

The “Global Day of Action” saw similar protests erupt in major cities around the world on Saturday.

“It’s a matter of time. We are hoping that this attack will expedite the process and the people can be finally back in the streets and take it all the way to the ultimate regime’s downfall,” said Pahlavi.

He shared that he hopes President Trump will have the United States intervene and “have the people’s back.”

On Friday, President Trump said regime change in Iran would be the “best thing” to happen while speaking to troops at Fort Bragg in North Carolina.

“People are hoping that at some point the decision will be made that there’s no use, there’s no point, we’re not going to get anywhere with negotiations,” said Pahlavi. “”Intervention is a way to save lives.”

South Carolina Senator Lindsey Graham was present in Munich for the security conference and echoed a similar sentiment in a sideline interview on Friday.

“There’s no negotiating with these people, in my view. They’re hell-bent on enacting an agenda based on religion that teaches them to lie, teaches them to destroy in the name of God,” said Graham.

He shared that the regime is the weakest they have been since 1979, adding, “it is a regime with American blood on its hand,” calling on protesters to “keep protesting.”

The senator also took the stage at the Global Day of Action speaking to the crowd and holding up a “Make Iran Great Again” black hat.

Large demonstrations were also held in Toronto, Melbourne, Athens, Tokyo, London, and Los Angeles.

An estimated 350,000 people marched on the streets of Toronto, the city’s police spokesperson, Laura Brabant, told the Associated Press (AP).

Iranian American activist and Beverly Hills plastic surgeon Dr. Sheila Nazarian told Fox News Digital the protests across the globe represent a universal truth. 

“When regimes silence their people, the people eventually find their voice. Whether in the streets of Tehran or in diaspora communities around the world,” she said.

Nazarian left Iran when she was 6 years old along with her family.

“As someone who came to this country from Iran, I know firsthand that these protests are not about politics, they’re about basic human dignity, women’s rights, and the fundamental freedom to live without fear,” she added.
