The United States has increased its military presence across the Middle East as diplomatic efforts with Iran face new uncertainty. Talks aimed at reviving negotiations over Iran's nuclear program have been moved from Istanbul to Oman following lobbying from several Arab leaders. Satellite imagery reveals a significant buildup of U.S. aircraft, naval vessels, and logistical platforms in the region, including an aircraft carrier strike group and various support aircraft at key bases. While experts caution that these movements do not necessarily mean a strike is imminent, they indicate a heightened state of readiness and a clear signal to Iran. Tensions remain high after U.S. forces shot down an Iranian drone near the Abraham Lincoln carrier, and officials emphasize that any future talks must address a range of issues beyond nuclear activities.
