Retired IDF Colonel Dany Tirza, was instrumental in building the security wall at the boundary between Jerusalem and the West Bank.
The fence is 451 miles long and was initially budgeted at 3 billion shekels, eventually coming in at 11 billion.
But as Tirza explains, the process of erecting a wall to keep your borders secure, involves much more than just building a barrier.
Since building a wall between the U.S. and Mexico is such a hot button issue on our side of the world, I asked Dany whether he had any advice for the Trump administration.
Watch as he explains the key to building a security wall that works.
