Re: ....., history si!
We work hard at selling the American Dream. Poor Israel, being a young nation at its re-birth, looked Westward to the US.
The US built no wall to protect from the ravenging Indians, they just rolled over them and built subdivisions.
Throughout history no nation has built a wall to protect them from enemies they have defeated or they feel they have the ability to defeat. Conquest at arms has always carried the reward of possible expansion as a side virtue.
Has history taught us bad lessons? Perhaps. But they have show how success and failure function.
