If President Donald Trump tuned in to Fox News after ordering Thursday night’s successful U.S. operation to kill Maj. Gen. Qassem Soleimani, the commander of Iran’s elite Quds Force, he heard nearly unalloyed praise of his decision along with claims that any U.S critics are siding with the Iranian regime.

Soleimani, who oversaw proxy wars in the Middle East which included numerous attacks on U.S. forces in the region, has been described as Iran’s “most important military commander” and an “indispensable” figure in its government. The Pentagon has claimed (without providing substantiating evidence) it killed Soleimani as he was “actively developing plans” to attack American diplomats and service members and that the strike “was aimed at deterring future Iranian attack plans.”

Soleimani’s killing is a seismic event in the region that signals the U.S. may have entered an undeclared hot war with Iran. The complex international situation will require prudent management because of the substantial risk of retaliatory attacks spiralling into deadly escalation. And as Trump responds to the crisis in the days and weeks to come, his steady consumption of Fox programming and the consultations he has with the network’s hosts will shape his worldview and thus help determine U.S. policy.

That means Fox’s shows provide a window into the advice that the president is receiving from some of his most trusted advisers. And in the wake of Soleimani’s killing, Fox’s hosts and guests are telling the president that he did the right thing, that the risks of the assassination backfiring are low, and that anyone who says otherwise is effectively a traitor.

Sean Hannity, a Fox host and close ally of the president, called in to his own show from vacation Thursday to say of the killing, “This is a huge victory for American intelligence, a huge victory for our military, a huge victory for the State Department, and a huge victory and total leadership by the president.” He and guest host Jason Chaffetz stressed that killing Soleimani after recent Iranian-backed protests at the U.S. Baghdad embassy showed that Trump’s response was superior to President Barack Obama’s after the attacks on U.S. diplomatic facilities in Benghazi during his administration.
