Building A Useless Wall, Or Not

THE PROBLEM with building an impervious, impregnable,  impermeable wall from sea to shining sea along the entire length of the Rio Grande, as has been pointed out by America's political left and the lessons of history, is that it would not work. That, aside from teh fact that neither we the american people or government has the conviction and political will to undertake such a massive project, as evidenced by the fact that trump insisted, falsely, that the wall would be paid for by Mexico. mexico refused, and that was that. History hath shown, as Jefferson might have said, that walls are ineffective, that they only temporarily impede travel, rather than prevent it. Patton agreed. Fixed fortifications are monuments to the stupidity of man, was his remark. the ancient Romans proved that tenet quite well at Masada. the Maginot Line and teh great wall of China, for instance. The former the Germans merely circumvented, and the latter was effective only because it was monitored and defended twenty four seven by a massive contingent of soldiers atop it,and a communications system.The point is, the great wall of Trump would suffer the same limitations, and would required constant human monitoring and defense to keep out of desperate, hungry refugees seeking survival in the U.S., in the occupied territory which, but for american imperialism and conquest, would have always and would rightfully still belong to Mexico.The desperate, hungry refugees of brown skin so dearly hated by American conservatives and Trump supporters.The point is, why not save the expense of useless wall building and merely use the American army to monitor and defend the border, which is, after all, the actual purpose of armies? To comfort open border liberal types, bear in mind that an army need not necessarily be an aggressive organization, but is quite capable of being a welcoming force, and rendering assistance to anyone who needs it.
