Two oil tankers have been damaged in a suspected attack in the waters between the United Arab Emirates and Iran as they were leaving the Persian Gulf. This is the second incident in four weeks, and raises the question of who gains what from them.

Fingers will certainly be pointed at Iran as the mastermind behind these events. But the potential benefits to the Persian Gulf nation are outweighed by the risks. And even if Tehran isn't responsible, it will still suffer the consequences.

The first tanker to report a problem was the Front Altair. It was reported to be carrying 75,000 tons of naphtha, loaded in Abu Dhabi, to Japan, although it was signaling a destination of Kaosiung in Taiwan when it was damaged. The second vessel was the Japanese-owned Kokuka Courageous, which was sailing from Saudi Arabia to Singapore with a cargo of methanol.
