Why build the US-Mexico border wall?

The US-Mexico border refers to the border between the United States and Mexico, starting from San Diego and Tijuana in the west and reaching Brownsville and matamoros in the east.

10 On June 26th, US President Bush signed a bill authorizing the construction of a wall on the US-Mexico border, aiming at preventing a large number of illegal immigrants from entering the United States from the Mexican-American border by building a wall that stretches for thousands of miles.

The new bill not only approves the construction of a 1 126 km long wall in the US-Mexico border area, but also authorizes border law enforcement officers to deploy more mobile fences, open more checkpoints and erect more lighting equipment to prevent people from illegally entering the United States. In addition, the bill also authorizes the Department of Homeland Security to use more advanced means such as cameras, satellites and drones to strengthen security in border areas.

Recently, the US media quoted an internal report of the US Department of Homeland Security as saying that President Trump's plan to build a wall on the US-Mexico border will cost as much as $21600 million. This figure is much higher than the $654.38+02 billion declared by Trump during his campaign, which caused media doubts.

In response, US President Trump 1 1 responded on social media that he has not participated in the design or negotiation of the border wall. When he is involved, the construction cost will drop like the previous F-35 fighter and Air Force One project.

Earlier, US President Trump criticized Lockheed Martin for being "out of control" in developing and manufacturing F-35 fighters through social media. Subsequently, Lockheed Martin reached an F-35 procurement contract with the US Department of Defense at a low price on the 3rd of this month.
