DUBAI/JERUSALEM/PALM BEACH, Florida: U.S. officials responding to economic uncertainty over high oil prices predicted on Sunday that the U.S.-Israeli war on Iran would end within weeks and that a drop in energy costs would follow, despite Iran's assertion that it remains "stable and strong" and ready to defend itself.

U.S. President Donald ​Trump threatened more strikes on Iran's main oil export hub Kharg Island over the weekend and said he was not ready to reach a deal to end the war which has shut off the vital Strait of Hormuz and shaken up global energy markets.

The Trump administration plans to announce as early as this week that multiple countries have agreed to form a coalition to escort ships through the narrow waterway but they are still discussing whether those operations would begin before or after hostilities end, the Wall Street Journal reported, citing unnamed U.S. officials. The White House did not immediately respond to a request for comment.
