Yet even this tremendously lopsided tactical situation has no guarantee of failure for the Iranian attempt to deliver more potent weaponry to its Houthi proxy warriors led by IRGC officers in Yemen.
Update 6:45 PM: The media reports stating that the Iranian ships turned around because they realized that US ships were tacking them is pure, unadultered Obama Administration cow pie. The Iranian's turned back to the north not because they feared the assembled fire power of US naval forces, but rather they realized they were no match for the Saudi and Egyptian ships with which they would have to do the dance of death if they tried to offload weapons to the Houthis. This is where Iran finally realized the limitations of its capability in raw military power projection, and they were summarily defeated by the Sunni Arab Navalforces without a single shot being fired. This is big.
