Yes, you need to play the madman. The IR will never do that because the oligarchs inside Iran have too much wealth in the Emirates, Europe and North America.
And Iran cannot play the madman without nuclear deterrence.
Indeed. The problem is that Iran had a window of opportunity to do that in the early years of the 21st century while the US was in a quagmire in Iraq and Afghanistan and Iran decided to waste all those years and eventually surrendered to the US and Europe by signing the JCPOA.
That's what I think too. The oligarchs would profit from the blockade for sure. They will earn hundreds of billions of dollars, turning Iran into a failed state.
Soleimani wasn't the person who said no to nuclear weapons and ICBMs. He expanded Iran's regional influence as much as he could. He was a victim of Khamenei's idiotic policies, not the source of the problem.
Meanwhile, on a side note, Turkey signed a defense pact with Qatar today. The entire region is uniting against Iran one by one.
