Clearly the seizing of the ship is a UK failure. Our flag, our protection. One can blame it on underfunding of the military if one likes, but we are in austerity aren't we ? Budgets are tight. Or one can blame lack of preparation. We stop an Iranian vessel that is under suspicion of doing something illegal, yet have insufficient force in the area to avoid illegal action by Iran in retaliation. Maybe we should have arranged US military help to be in the area as part of the agreement to stop the suspect craft.
