Went through the entire article and the entire list of countries listed - not a single wall or border across the ENTIRETY of the border. You can prove me wrong by citing otherwise.
The very chart in the article disproves your assertion
Do you see any country with a wall or a fence through the entirety of the border?
Again, barriers and fences on certain locations - NOT a wall across entirety of the border. This is from your own article.
Washington Examiner which printed a list of lies from the Trump admin is as usual lying here as I proved earlier.
They cite for example India and Bangladesh when I conclusively proved that more than 700 km of their border does not have a fence or a wall.
You tried and you failed because absolutely no country has a wall across the entirety of the border, it's just plain stupid and ineffective.
