In response to the recent spate of Iran-linked attacks in the Persian Gulf, the United States has laid out on an initiative to secure oil tanker traffic in the area, while providing better visibility and attribution for any future incidents. Coined the Sentinel program, the operation would involve deploying additional warships and maritime patrol aircraft, as well as placing cameras and other surveillance devices on crude-bearing vessels transiting through the region. To help lessen the strain on U.S. resources, the White House is attempting to corral the support of both regional and global allies who also risk having their oil supplies disrupted by Iranian attacks. But doing so will be no easy feat, as Washington's sanctions-heavy approach to Iran in the past year has alienated even its closest partners.
