In 2006, during the Bush administration, the U.S. government intended to install a fence along the Mexican-U.S. border. The controversial proposal involved the creation of many individual fences. Nearly 600 miles (966 km) of fencing was constructed, each of which consisted of steel and concrete.  Between these fences are infrared cameras and sensors, National Guard soldiers and SWAT teams on alert, which produces the term “virtual fence”.”  Construction of the fence began in 2006, with each kilometre costing the U.S. government approximately $2.8 million.  In 2010, the initiative was abandoned for cost reasons, having travelled 640 miles (1,030 km) either from barriers, new barriers or rebuilt over old, poor-quality fences. The SBI-Net systems built by Boeing for the use of radars, watchtowers and sensors (without barriers or physical barriers) were scrapped because they were over budget, full of failures and well below schedule.  Now, there are other communities that are about 150-60 miles from the border, who see the same thing as Border Patrol dropping off individuals in places like San Antonio, Texas. The city of San Antonio is now facing a situation where they put money in their pocket to tackle some of these problems where they drop people into the thousands of them at bus stops, and someone has to come and manage them.
And I think that if we just sit down and talk to each other and understand what the fundamental contours of this agreement will be, I am convinced that we can achieve that. Criticism of Operation Streamline indicates that the program makes extensive use of Federal Court of Justice resources and implementation resources.  In addition, the continuation of all illegal border crossings has focused on the continuation of serious offences.  They argue that the cost of the program is too high for the effectiveness of the work it does.  In response to the assertion that Operation Streamline is an effective deterrent, critics of the program argue that incentives to cross the border to work or be with family are much stronger.  Such figures would have significantly limited the number of asylum seekers who have daily access to U.S. ports of entry, which are already under extreme pressure due to resource scarcity, security crises and the “metering” system put in place by U.S. border guards.
To avoid this, the Mexican government should quickly provide services in these areas and develop procedures for transferring asylum seekers returning from the border to other parts of Mexico. As part of the U.S.-Mexico talks, the Mexican government agreed to provide “jobs, health care and education” to returning migrants; However, the Mexican governors of the northern border states indicated that they had not yet received information on how the program would be implemented in their states or on the type of assistance they would receive. In fiscal 2018, U.S. border guards arrested a record 107,212 people traveling with families. Over the next five months (October 2018 to February 2019), this record was shaken by the arrest of 136,150 family travellers.  On March 31, 2019, Trump threatened to close the border and cut off trade between countries.  On April 4, Trump said he would give Mexico a year to prevent illicit drugs from entering the United States.
