To built the Wall at the Border between The United States and Mexico, approve a New Immigration Law in the United States and negotiate a new Migration treaty between the United States and Mexico is a moral imperative. Not to do so is immoral. Not to do so is sin. The present, de facto, reality of open border between both nations is creating an environment of illegality that supports and feeds all kinds of illegal and immoral trafficking across that border. A wall; big, huge and well supported by other efforts and technologies, will reduce and force all that trafficking to be done thru the official ports of entry between both nations, where all the latest and strongest measures can be taken to prevent it.
But the Wall by itself, no matter how big it is, will not stop the illegal and immoral trafficking across the border. The United States needs a new immigration law updated to the reality and the technology of the 21st century. The goal should not be to prevent foreign people from entering the United States, but to regulate the immigration process in a way that is practical, ethical and enforceable. Even more, and recognizing the National Sovereignty of Mexico, that law should be approved in harmony with a new migration treaty between the United States and Mexico that will harmonize the National interests of both nations, and will guarantee that both nations will work hand in hand to enforce the treaty and make it successful.
A Wall at the Southern Border. A new Immigration Law in the United States. A New Migration Treaty between the United States and Mexico. All three are needed. Theory, ideology and moral principles should be taken into consideration, but ultimately the law must respond to the REALITY at the border, and how it is affecting the life of Americans and the American Society there. Of course, the well being of Mexicans should be a priority for the Mexican Government. They should revise their migration policies and seek to negotiate a new Migration treaty with the United States that takes their needs and national interests into consideration.
No one side, national or political, should seek to impose his point of view upon others, but should negotiate seeking the best overall practical solution. In my humble opinion, the wall: big, impregnable, huge, should be an integral part of that solution.
