During Donald Trump’s campaign for the presidency, he promised he would build a “beautiful” wall on the border between the United States and Mexico and that Mexico would pay for it. It was one of his guaranteed applause lines. He never said how he was going to get Mexico to pay for it, or why they would agree to do so, but that didn’t seem to matter. He was going to build it and they were going to pay for it.
Now that he is president, things are a little trickier, since now he has to build the wall – and he has to get Mexico to pay for it. One of his first equivocations was that we would pay for it initially, but he would get Mexico to repay us later. Once again, he didn’t say how he was going to get Mexico to repay us, but that was just details – or something.
