A 'fence' does not cost $1,500,000,000.00. Either what is proposed is not a fence, or it will not cost 1.5 billion dollars. Just out of morbid curiosity, I decided to work this out. I found a quote to install cyclone fencing -- materials included -- for $2.60 a linear foot. That comes to just under $14,000.00 a mile. The Egypt-Israel border is 125 miles long. That comes to 1.75 MILLION dollars to fence the whole thing -- or one thousandth of the cost quoted here. Obviously, it's a harsh environment, and this presumably is going to be a government operation, but no -- whatever you're calling a 'fence' is definitely not a fence.
