The fragile ceasefire between Israel and Iran appeared to be holding on Wednesday after a rocky start, giving rise to cautious hope that it could lead to a long-term peace agreement even as Tehran insists it will not give up its nuclear program.

The fast-changing war between Israel and Iran, in which the U.S. recently inserted itself by targeting Iran’s nuclear sites, has caused a mix of emotions — including fear and uncertainty — among many in the Iranian diaspora in America and also showcased differences of opinion over the country’s future.

The head of the Israel Defense Forces said Tuesday that “the campaign against Iran is not over” as a ceasefire between the two countries went into effect. President Donald Trump also vowed that Israel will not attack Iran and told Israel to bring its pilots home.
