TEL AVIVIsraels Prime Minister Benjamin Netanyahu on Saturday praised plans by U.S. President Donald Trumps new administration to build a wall on the Mexico border, saying his countrys own barrier on the Egyptian border had halted illegal immigration. I built a wall along Israels southern border. It stopped all illegal immigration, Mr. Netanyahu wrote on his official Twitter account, adding emoticons of the U.S. and Israeli flags. Great success. Great idea.
