Most probably.

Edit: I wouldn't be surprised if they ended up using nukes.

His handlers are neocon Zionists and they are itching to destroy Iran

It could also be cope due to him wanting to be remembered for something big. The atomic bombings were massive, and will stand throughout history as the first, and so far (and hopefully), the only time nuclear weapons were used on civillians. Sure it may have stopped the war, and that may be what Donald is equating it to, however I do feel he wants to be remembered throughout history for something good. His ego needs it, he needs it. No-one else has plastered their name over buildings and coveted gold and other gaudy decor options. Nothing more than a narcissistic moron who wants to be remembered throughout all of time as the greatest person to have ever lived.

During his feature length interview in The Fog of War, MacNamara said explicitly that if they had lost the war, he and his team would have been tried for war crimes. He cries a bit at one point while describing the firebombing of wooden cities, at how it was worse than the atomic bombs they dropped.

I’d love to ask him “for any type of weapon you use, would you be okay having it used on you?”
