The action tested an interim understanding reached about a week earlier as the two countries began working to end months of fighting and reopen the strategic waterway. U.S. Central Command said the military targeted missile and drone locations and coastal radar sites in Iran, and a U.S. official said the strikes concluded about an hour after the announcement. Trump told reporters shortly before the action that multiple shots had been fired the previous day, and he cut off questions when asked why strikes would occur while talks were said to be going well. Iran\u2019s Ebrahim Azizi, who heads parliament\u2019s national security commission, said the strait is governed by Iran and characterized the situation as \u201cceasefire management,\u201d not a violation.<\/p>\n<h2>Polymarket Data: $2.44M Volume and Yes 54.0% (Up From 25.5%) on \u201cUS-Iran Final Nuclear Deal by Dec. 31, 2026\u201d<\/h2>\n<p>Polymarket\u2019s ladder market \u201cUS-Iran Final Nuclear Deal by\u2026?\u201d shows the December 31 strike as the top line, with Yes at 54.0% and No at 46.0%, up from 25.5% previously for that leading outcome.
