I agree with you, you would think not, especially with their vast intelligence services as well as the Israeli's assisting them and also Iran's history of conflict from the past.... but then you are basically saying that the US deliberately went ahead and started this war with Iran, knowing full well what would happen with the Straits of Hormuz... without planning anything at all to counter that response from Iran, just because they wanted this war with Iran .....
No I don't think it was Trump's intention. I think the military and intelligence services would have likely spoken up and passed their assessments up the chain of command...whether it reached Trump or not is another thing...but I suspect it did. What I expect happened was that another set of advisors gave him a totally optimistic best case scenario that this would be a quick and easy operation, drop a few bombs the Iranian's will run to the negotiation table, it will be just like Venezuela. Still on a high from the the success of the Venezuela option that is the scenario he wanted to believe so he chose it.
That is very possible, but then again, if Trump went into this war with his own top secret reasons, then sharing those reasons with NATO "may" have changed their reasons or attitude towards a war with Iran..... and no, we will both never know the real answer to that for sure, but we cannot categorically say it couldn't or wouldn't happen.
Trump was wrong for not even informing anyone at NATO of what he wanted to do by attacking Iran, never mind also wanting to include them beforehand.
If he went into the war with his own top secret reasons...then the intelligence services and members of intelligence committees would have long since come out and said the reason's exist, we just can't share what they are at this time. If such intelligence existed...it's like allied intelligence services would also have been able to corroborate the intelligence at least to some degree. Also if such intelligence existed...do you really think a country like Britain couldn't be trusted to share the intelligence with.
The far more likely explanation is no such top secret reasons exist.
I don't think he wants to control the oil, he just doesn't want a manipulated oil market where China and their cronies can buy sanctioned oil at a massive discount...a fair open market, hence the lifted sanctions. Sanctions had the opposite effect than intended...give all the rogue countries an edge while the West got the punishment at the pump.
The oil markets were doing just fine before Trump's little escapade. The straight was fully open, global supply was normal and volatility was low. There was no expectation or reason to believe Iran would of just shut the Straights of Hormuz if not but for this war.
