The head of Iran’s Revolutionary Guard on Monday accused Saudi Arabia of treachery against the Islamic world and compared the kingdom to Israel saying, “Saudi Arabia is shamelessly and disgracefully bombing and mass killing a nation that is fighting against the arrogant system,” or world powers. Iranian leaders have repeatedly criticized the airstrikes and said the Saudi-led campaign is doomed to fail. Sunni Saudi Arabia and Shiite Iran are longtime regional rivals. They back opposite sides in Syria’s civil war and are fiercely divided on a host of regional issues. This makes me wonder if this would lead to a war between the two nations eventually.
