Comment: NAFTA is a failure in many ways except one, it provided the Mexican drug cartels with more access to the U.S. by using long haul trucks to carry drugs from Mexico across the border. According to Mexican officials the cartels, as a result of NAFTA now ship roughly $ 64 billion dollars in drugs annually to the U.S. 
In 2010 NPR reported that 4,800 trucks a year pass over The World Trade Bridge, the biggest commercial port on the southwest border, one truck every 15 seconds. 
In 2015 the Obama administration further enabled the cartels more access by allowing long haul trucks from Mexico to make deliveries into the U.S. accounting for 78% percent of security breaches at U.S. border crossings. 
Previously only trucks carrying produce from Mexico were inspected at U.S. borders, that has now changed – all trucks coming from Mexico will be inspected. The cartels are now claiming themselves ‘victims’ of Trumps new border policies as their access through U.S. border crossings have been seriously reduced – the result of another promise kept by President Trump….WFM

In a major shift from lax Obama-era regulations, the Trump administration is finally allowing customs officers to screen all cargo trucks entering the U.S. from Mexico and sources on both sides of the border tell Judicial Watch Mexican drug cartels are fuming. U.S. Customs and Border Protection is using X-ray technology and other non-intrusive tools to screen 100% of cargo trucks crossing the southern border after eight years of sporadic or random screening permitted under the Obama administration.
“We felt like we were the welcoming committee and not like we were guarding our borders,” said veteran U.S. Customs agent Patricia Cramer, who also serves as president of the Arizona chapter of the agency’s employee union. “The order was to facilitate traffic, not to stop any illegal drugs from entering the country,” Cramer added. “We want to enforce the law. That’s what we signed up for.” Cramer, a canine handler stationed at the Nogales port of entry in Arizona, said illicit drugs are pouring in through the southern border, especially massive quantities of fentanyl, an opioid painkiller that the Drug Enforcement Administration (DEA) says is more potent than morphine.
Approximately 471,000 trucks pass through the U.S-Mexico border monthly, according to figures published by the U.S. Department of Transportation. The busiest port of entry is in Laredo, Texas where 167,553 trucks enter the U.S. from Mexico monthly, followed by Otay Mesa in California (76,953), El Paso, Texas (58,913), Hidalgo, Texas (45,355) and Nogales with 29,439. Other busy ports include East Calexico, California (29,173), Brownsville, Texas (16,140) and Eagle Pass, Texas (12,952). Trucks bring in everything from auto parts to appliances, produce and livestock. In fact, a veteran Homeland Security official told Judicial Watch that cattle trucks passed without inspection during the Obama administration because Mexican farmers complained that the security screenings frightened their cows. “Our guys were livid that we were not allowed to check cattle,” the federal official said.
Frontline customs agents stationed along the southern border confirm that trucks containing “legitimate” goods are often used by sophisticated drug cartels to move cargo north. This is hardly surprising since most illegal drugs in the United States come from Mexico, according to the DEA, and Mexican traffickers remain the greatest threat to the United States. They’re classified as Transitional Criminal Organizations (TCOs) by the government and for years they’ve smuggled in enormous quantities of heroin, cocaine, methamphetamine and marijuana. Last year the Congressional Research Service (CRS), the nonpartisan agency that provides Congress with policy and legal analysis, published a disturbing report outlining how Mexican cartels move record quantities of drugs into the U.S. Because cartels move the drugs through the Southwest border, western states have become part of what’s known as the “heroin transit zone,” according to the CRS.
Federal law enforcement sources tell Judicial Watch Mexican cartels operate like efficient businesses that resort to “other more treacherous routes” when necessary, but driving through a port of entry in a cargo truck is a preferred method of moving drugs. Cartels station shifts of spotters with binoculars in Mexican hills near border checkpoints to determine the level of security screenings. “They know if we’re on the job, the level of screening that we’re conducting,” Cramer said. “The cartels watch us all the time.” Nogales is a favorite for cartel spotters because the U.S. checkpoint sits in a valley surrounded by hills on the Mexican side, where unobstructed views facilitate surveillance. “They see everything,” Cramer said. For years the cartel spotters saw that much of the cargo passing through the checkpoint was waved through, according to agents contacted by Judicial Watch.
