Though the ceasefire between Israel and Iran has been holding, 'The war remains an unfinished project, for both sides,' one Middle East expert warns.

Some experts said they believe the U.S. strikes have the potential to lead to a "fork-in-the-road" moment that could result in Tehran taking an even more dangerous path.

Iran's Supreme Leader Ayatollah Ali Khamenei attended a religious event on Saturday, according to a video carried by state television, after reports that he was in a "secure location" since the start of a 12-day air war with Israel in which top Iranian commanders and nuclear scientists were killed.

Critics feared it would plunge the Middle East into a wider war. That doomsday scenario has not come to pass, at least for now: Iran made only symbolic retaliation against America; soon after, a ceasefire ended the fighting between Iran and Israel.
