Trump just shot themselves in the foot.
I don't know how much the rest of you know about Iranian culture (I'm an expert), but religious zeal and martyrs are huge parts of it. It's not like it is in Nazi Germany where you can become successful by being one general that decides to take over. If you try to take over in Iran, you bring shame to yourself, and the only way to get rid of that shame is Civil War.
What this means is the iranian public, after hearing about this, is not going to want to purchase Freedom from either America or Israel, nor will they build any of Trump's hotels. This is HUGE. You can laugh all you want, but Trump has alienated an entire market with this move.
Trump, publicly apologize and cancel World War 3 for Middle East or you can kiss your real estate empire goodbye.
