According to then candidate Donald J Trump's proposal, the US should build a wall on its southern border with Mexico. Seems every time he mentioned the wall in his rallies, his crowd cheered and were motivated. Recently some Texas Republicans suggest that there won't be a physical wall and instead, it is more of Trump's metaphor of strengthening border security. However, Trump did say the wall will be an "impenetrable, physical, tall, beautiful Southern border wall" (Phoenix, Arizona rally) and signed an Executive Order to start constructing the wall on January 25, 5 days into his first term presidency.
Now that building a wall is the reality, I came up with several methods that are better than a wall, and wonder why these methods, which could be cheaper and more effective, are not being considered by the White House:
- A fence similar to the Saudi-Iraqi border fence or the high-tech Israeli-Sinai one. Because a metal fence is easier for installing/attaching devices capable of detecting large animals (including human) climbing on it. Also it is less expensive than a concrete wall that the Trump campaign proposed to Miami-based condo developer Jorge Pérez.
- According some media, the wall is much more expensive than what the Trump campaign claims, because there are extra border security involved. Now in March 2017, according to the Los Angeles Times, Trump administration is going to "rapidly expand" the number of Border Patrol agents by 5000. As I understand these agents are federal employees and enjoys pensions and other benefits that are paid by tax payers. Why not instead ask Governors from border states to mobilize their National Guard or State Highway Troopers to patrol their respective sections of the border during seasons with higher number of illegal crossings?
- How about a mine field that is not near any official border crossings, similar to the DMZ between North and South Korea?
I personally feel that constructing a concrete wall will be not as effective and could be a waste of federal tax revenues, but the wall proposal is popular among US voters at the moment and during election seasons 2016, any explanations?
