Read your history. What caused the surrender?
Option 1: Invade the country with +million troops, forcing surrender
Option 2: Drop a nuclear warhead(s) on country, forcing surrender
Option 3: Blockade and isolate the country so it would be starved of food and resources, forcing surrender
Option 4: Negotiate after extensive bombing, which may or may not work
Trump has similar choices and the first 3 have significant downsides
When Truman was done with Japan, Emperor worship ended, they were disarmed - it was an unconditional surrender.
47, in contrast, will be leaving the Mad Mullahs and it's IRGC rule intact, no gain there. Since the Strait was open before 47 attacked, no gain there. The nuclear material may be recovered and disposed of - a gain. That's it. The limited nuclear gain will be immediately recovered once 47 is gone. The regime will then be free to murder as many Persians as they please. And make as many nukes as they want.
And of course, Iran will be hailed as a great power since the regime remained intact - they survived the attack of the Great Satan!
Islam will redouble its efforts to conquer, once again, the entire Western world and enter a 2nd Dark Age. The Future will only know 47 as the man who helped Islam conquer the world - if he's not forgotten entirely.
