As much as I want to discuss whether GCC would do it or not, I can't tell you what the future is; I can only interpret the current situation and project the future.
And from the latest info, after they had sunk the Dena, there is just 1 Iranian frigate left (not counting the old british made Frigate). If they are just about bombarding Iran, they don't need to deal with the Frigate, and now they went over the edge to sink Dena (it was being hunted), that means they are prepping the battlefield for something, Frigate usually used in ASW and Anti-Surface warfare. That indicate an Naval Op is brewing.
