Sounds  like the words "legal immigration" still have no place in your vocabulary. And 20 other countries built walls are now trying to stem the invasion from the Middle East by Islamic hordes who never even consider assimilation. The refugees of war and military age with no wives or children  continue to invade, as has the onslaught by Islam on Christian lands, for the last 1,400 years. I am thankful for my relatives who fought these Islamic animals for over 250 year in the land of the Dragon.
