These peoples are shooting all the shots to be reelected, and to be elected. Just check the arsenals of the USA, they have more than that, North Korea is a small grocery store compared to the USA arms warehouse and hackers. Now they want to impose tariff on the cars crossing from Mexico to pay for the wall after they defunded all the Federal agencies to finance ( election campaign promise ) the wall but peoples coming thru that border toward the north are USA citizens who travel to Mexico to buy medications and to recieve dental and medical attention, or are living in Baja California and they travel to San Isidro to pick up their medications. There is a big exodus of Mexicans returning to Mexico due to unemployment, and some reports have indicated that the traffick of drugs have becoming larger after the mexican wall, and more drugs cartels are being created, it is a profitable business like any other business which produces the same amount of profit, or maybe more as petroleum
