If that's what it was, I don't think it worked. I think rather that Trump and Vance manufactured a conflict to use as pretense to do what they wanted to do in the first place, which was to cut off Ukraine from U.S. aid. Whether it flies with the American public generally is largely irrelevant to Trump at this point, as he's not constitutionally eligible to run for another term. (He might simply refuse to leave in 2028, but he doesn't need an election to do that.)
