the blockade + air strikes against warehouses lower the count but it can always be lowered even more
cause the blockade is not a 100% thing, air strike aren't conducted on a regular bases
I saw an article on the news and it's doing a damn fantastic work, not 100% off course but still..
I don't remember hearing on a plan to create an anti-Katyusha system back in the 90's, the only counter rocket system in use in this region was the Patriot
the Iron Dome program started during the last decade in response of the firing to the southern cities of Israel bordering the Gaza strip
BTW, my big brother heard somewhere that in general the use of Iron Dome is more cost effective than letting the missile hit the ground
cause the damage outgrow the cost per unit to launch.
