Washington Post columnist and Pulitzer Prize-winning author Charles Krauthammer, now passed, recorded this last year. He asks can America solve its illegal immigration problem both justly and humanely? He says, yes, but it requires first building a border wall.
Countries which have built a border barrier
1. Bulgaria
The country built a wall along the Turkish border, which was completed in August 2015. It marks the beginning of the walling off of Europe, as some are referring to it.
2. Hungary
Hungary completed its wall along the Serbian border on 14 September 2015, and the wall along the Croatian border a month later.
3. Slovenia
Slovenia built a razor sharp fence, cutting across the Croatian border in November last year.
4. Macedonia
At the end of November, Macedonia completed a wall along the Greek border topped with barb wire.
5. Austria
In April of this year, Austria began construction of a ‘fence’ along the Italian border.
