U.S. officials and lawmakers eager to help President-elect Trump make good on his campaign promise to “build a wall” on the Mexico border are looking to the hastily built fence Israel constructed in just two years to stop the flow of illegal immigrants across its southern border.

The “barrier” fence between Israel and Egypt was built from 2011 to 2013 after thousands of Africans surged in, similar to what is happening on the U.S.-Mexico border now. The fence is made of hard-to-cut metal rods, topped with razor wire and enhanced with technology to identify break-ins.
