You won’t stop tunnels this way
From the op-ed:
"So what would be the result of stopping the sale of construction materials via Israel? First, the livelihoods of 70,000 workers who earn their living in the construction sector, either directly or indirectly, will be threatened. The construction sector represented 27% of Gaza's GDP in the second quarter of 2013. Second, the cost of building schools, homes and hospitals will continue to soar and projects will be delayed. Third, Israel will once again find itself holding on to the illusion of security at the cost of harming civilians in Gaza".
