Many comments in the comment section are completely irrelevant and illogical. My point was that the tweet I quoted raised the question of who controls and blocks the Strait of Hormuz. My message is that any country can control it, as long as it can harass and attack passing oil tankers, force insurance premiums to rise, and prevent ships from passing. Ultimately, it can achieve the effect of blockade and control, which is the last sentence of my tweet. Furthermore, some people are suggesting that it's simply a matter of not buying insurance. They should first go and check whether oil tankers can navigate without insurance! Do they really think that driving a multi-million dollar oil tanker carrying hundreds of thousands of tons of crude oil is like driving a BYD without insurance and swaggering around unchecked?
