If a country wants to continue to exist and invaders attempt to bum-rush its border, it does not announce $450,000 payouts to illegal aliens and forbid the Border Patrol from using horses. It defends the border. That is the primary purpose of a national government. Poland demonstrates as Muslims attempt to invade:

At the Gates of Vienna on September 11, 1683, Polish King Jan Sobieski saved Europe from the Muslim conquest that had erased Christian civilization throughout the Middle East. When his spirit dies out, so does the light.
