Yes, I agree. In the long run, President Trump wants a reasonably peaceful regime change in Iran, because that’s the only way to get rid of the Iranian nuclear weapons program forever, and have long-term peace and stability in our world.
This recent statement that he “doesn’t want regime change in Iran” just means that it’s not the right time now for a reasonably peaceful regime change without a civil war in Iran. This will all take some time...but 1 or 2 years is a short time in world history.
