Am I missing something here? (re: reopening of bars, etc... now)

In which part of the US have those strong shutdowns worked? I’m reading news out of California, and things there seem to be getting dire. They have had strong shut downs, and now they seem to be having to make them stronger. I’m more than happy to consider – to not ignore – the evidence that strong shutdowns work, but I don’t know of any in the US. I do see, however, that Florida has kept things open for a while and doesn’t seem to be doing any worse than California is at the moment. Or that South Dakota and North Dakota seem to be in the very same boat despite different approaches. I take it that none of that is convincing to you. Or that you disagree with that take in the first place.
