Donald Trump's wall is simply pandering to the masses. He is reading his own press. He cannot truly believe that building a wall will seriously address the complex issue of immigration. He cannot be that shallow, right? He speaks like he has always done, like he is still on his own TV show. He reigned supreme on his show. He decided on who would stay and who would go. He talks like that is exactly how he would run the country. And people are falling for this? How does he expect to run the country like this? He cannot simply impose his rule on the country and decide what is good and what is bad. Makes him no better than what we already have. So, back to the question. No. I agree with some of the other comments here...the Berlin and Great Wall, great answer and he cannot fire Mexico because they won't do what he wants them to do. Put more effort into making the process of legal immigration more attainable in less time. Maybe more people would follow the rules.
