China built a 10,000 mile long, elevated road wide enough for two soldiers to ride side by side along its top, thousands of years ago.
We can't build a simple fence???
Yeah. If China was successful with that, and we're not copying to protect our borders, that tells me that none of the scumbags want the border to be protected. Right now, we just have a flim-flam excuse going on, only there to appease...
