it is a small country with a lot of mountains. the mountains make Switzerland a more difficult military target. In addition, Switzerland never felt the need to go out into the world and conquer other countries.
by not allowing every tom, dick and harry to enter their country they have maintained their national integrity. we, on the other hand, have allowed just about anything that walks or crawls to move in.
here are some photographs of some of those we have allowed to move in letting us know exactly what they think of our great country........
