The US Spent $15 Billion on a Steel Wall to Stop THIS — and the Price Shocked Everyone!

The United States has built a massive steel wall along its southern border, with 9-meter-tall bollard posts with concrete cores driven deep into the desert bedrock. Crews carry out geological surveys, dig trenches through hard granite, install panels weighing tons, then coat them with anti-corrosion paint and reinforce the top with razor-sharp barbed wire. The wall improves border control, but it comes with huge construction and maintenance costs, along with significant impacts on the environment, ecosystems, and the lives of nearby communities.
