Yes. Of course. It ended the tanker war.

Iraq and Iran had been pissant slap-fighting over oil tankers for years. The tanker war ended with the Vincennes incident.

A "straw on the camel's back" would mean the war crime earned negative domestic political repercussions.

"Ending the Tanker War" is clearly not that. It was the deployment's objective so I fear there are ghouls who would celebrate it.
