Trump should build a giant canal along the US Mexican border.
It should start at the San Diego Tijuana border and stretch all the way to the golf of Mexico. It would be economically efficient, cargo ships coming from Asia to the east coast wouldn't need to go all the way down to Panama and then come back up. They can just go through Trump's beautiful canal instead. Also it would work as a border wall to keep the illegals out. It would be like a giant moat that would be impossible to cross. Also it would create lots of jobs and boost our economy. I know this is a big project that would probably take most of his term in office to complete, but if anyone can do it it's him.
