I mean, miscommunication happens. Trump didn't invent the plan, he was advised by others and gave the go-ahead. Then, his advisors drafted all of the details of the plan (probably in very short order). And of course, he didn't write the speech, someone prepared it for him. Afterward, the speech changed hands numerous times until some staff member loaded it into the prompter.
Someone definitely messed up, but it's hard for me to see how anyone could blame the speaker for this one. Assuming there's no partisanship, of course.
