WASHINGTON: Ahead of the US attack on Iran, President Donald Trump received briefings that not only delivered blunt assessments about the risk of major US casualties but also touted the prospect of a geopolitical shift in the Middle East in favor of US interests, ​a US official told Reuters. The launch of what the Pentagon called Operation Epic Fury on Saturday plunged the Middle East into a new and unpredictable conflict. The US and Israeli militaries struck sites across Iran, triggering retaliatory Iranian attacks against Israel and nearby Gulf Arab countries.

The official, who spoke on condition of anonymity, said the briefers described the operation to the president as a high-risk, high-reward scenario that could present a once-in-a-generation opportunity for change in the region.
