With what weapons? Rocks and their bottle rockets are going to do much damage.
The Palestinians have 20,000 M16's from the USA, and Sniper rifles with CIA training, for peace of course. They have tens of thousands more AK47's from the peace process thanks to Clinton talking Israel into supplying Arafat. They have over a Billion bucks to buy fresh toys from Iran, which has been shipping military artillery rocketry by the ton over the Once monitored UN border, till the UN ran away with Egypt.
The daily shelling with rockets by Israeli towns is not bottle rockets, as they are blowing six foot holes in reinforced concrete roofs. The Russian Anti-Tank rounds are pretty effective, beyond the normal IED crap that goes on all the time. Face it, a 40,000 man army in uniform with automatic weapons is a bit beyond bottle and rock throwing that is only done for the Media. But the media game works, hey, you bought in to it.
These "bottle rockets" are the Russia made Saggar wireguided Anti-tank missile. The missile can hit a target at distances between 500 meters and three kilometers, and penetrate 400mm of armor. This picture is of units captured from the Palestinians.
