The Houthis only have drones and no cruise missiles like the Shiite rebels in Iraq. Recently, Iranian cruise and ballistic missiles (Fateh, Zelzal, and Ghadr and Sejil from the Shahab series) have grown in accuracy and sophistication. President Trump, on the other hand while mired in the impeachment storm, cannot afford another war in the Middle East and endangering the global oil supply in an election year. Apparently, the war for Saudi oil on which the US has less if no dependence considering the American shale oil production does not make sense. In the broader picture, the US would tolerate the Iranian military threat to keep selling arms to the Arabs and remain relevant.
