Will the Middle East destination dominoes continue to fall? Iran has scaled up its war of words, threatening to close the Strait of Hormuz, if the United States and its allies introduce more sanctions on Iranian oil exports.

Tehran has also warned a U.S. carrier group not to return to the Persian Gulf. Meanwhile, other media reports suggest that the U.S. and its allies are running out of options for how to deal with Iran.
