Hezbollah's Rockets

So what's Israel up against? Apart from the Katyushas, other rockets targetting Israel are the Fajr 3 and 5, Shahin 1 and C-802 Silkworm.



A fairly formidable inventory, thanks to Syria and Iran.

But the moot question is why isn't Israel using their much vaunted Patriot missiles against them? If they have deployed them, then this doesn't seem to be having much affect.
Just another expensive toy?

According to CNN the Patriot missles aren't capable of intercepting these missiles.
