Herezy that's the potential range of the rockets. But they rarely, if ever, reach that seeing as they are largely home made pieces of junk.
They have been supplied rockets in the past from other nations. And last time they hit Tel Aviv a few times. But the capability is still minuscule.
Still 1 Israeli death compared to several hundred Palestinian deaths so far. Regardless of Israel's 'early warning' they are still the aggressor in this conflict as it all stems from their actions towards Palestinians from day to day.
Dropping leaflets on a site will only be so effective and they only have access to telephoning 100000 Palestinians out of over 1 million.
