I've been reading Krugman since 2005. Of all the reviews I've read about Trump's speech last night, my opinion is that Krugman's take is the most accurate:
"It turns out that the speech was sort of an anticlimax, although not in a good way. Many people expected Trump to pull the mother of all TACOs, to declare victory and surrender. He did not do that. He declared victory, of course, but he did not actually announce an end to hostilities. On the contrary, he said we’re going to bomb Iran into the Stone Age.
So add massive war crimes to your schedule. There is clearly no strategy here. There’s no endgame. There’s nothing. It’s hard to tell, as always, whether Trump is delusional or just completely unable to admit something that he actually knows.
One of the moments that really struck me in the speech was him declaring that the whole world was extremely impressed by what happened. He said, the whole world is watching and they can’t believe the power, strength and brilliance. They just can’t believe what they’re seeing. The world can’t believe what it’s seeing.
What it’s seeing is that the world’s greatest military power took on a fourth-rate power. Again, as I said the other day, Iran’s military budget is a rounding error in our military budget. And we lost. For all practical purposes, we’ve left ourselves in a much weaker position and Iran in a stronger position than it was before."
This is how the world sees Trump:
