Protesters rally in front of Los Angeles City Hall against military action and war in Iran on Sunday.

On Sunday, demonstraters gathered at the federal building in Westwood to rally against the United State’s involvement in the conflict.

People held signs reading “No War on Iran,” and “We won’t let you drag us into global war.” Others chanted “hands off Iran,” and “Money for jobs and education. Not for wars and occupation.”

The recent strikes, Yaghoubian argued, targeted infrastructure belonging to the Islamic Republic. The US attack hit three nuclear sites in Iran: Fordow, Natanz, and Isfahan.

“These infrastructures, roads, factories, buildings, they can rise again, but what we can never recover are the lives of all young men and women we’ve lost to the brutal regime every time they rise for their basic rights,” Yaghoubian said.

War isn’t something people wanted, but Yaghoubian believes something good could come out of it — the end of the Iranian regime. The attacks represent hope for a better future, she said.

“No negotiation, no appeasement will bring an end this war. Only with removing this regime from Iran will bring peace and prosperity, she said.”

But Farahanipour doesn’t think the attacks will free Iran. He has advocated for a secular Iran, and the “internal toppling” of the Islamic Republic by Iranians. The activist believes the US should not have thrust itself into the conflict.

“Killing the people, regardless in Iran, in Israel, American people, anyone, any civilian or people, they just died, is not an answer,” he said.
