How Drama On The High Seas Could Spark A U.S-Iran War -- Robert Dreyfuss, The Diplomat

A recent incident with Indian fishermen shows how easily Iran and the U.S. could slip into a conflict neither wants but may find hard to avoid.

Once again, there are worries that Iran might attempt to close the Straits of Hormuz in a confrontation with the United States or, even less likely, in retaliation for U.S. and European economic sanctions against Iran.

In Washington, though, Iran’s rumblings aren’t taken too seriously: Not only is it unlikely that Iran’s navy could actually close the straits, but it utterly lacks the capacity to sustain a battle at sea against what would be an all-out counterattack by U.S. naval forces to clear the waterway.

My Comment: Both Iran and the U.S. know the red lines that they must not cross (the Indian fishing boat did not). If an incident occurs that causes a shooting war, it would be because one of these sides made the decision to "cross that red line".
