But they're not shooting these rockets at the Israeli army, are they?
The smallest Quassam warhead is 5 kg. The Grad's is 20 kg. The Fajr-5 has a 90 kg warhead and is 6.5 meters long. Often these contain ball bearings or other shrapnel, which are not weapons designed for military targets.
These are artillery rockets. None of them have guidance for specific targets. They are fired randomly at cities, not military targets, and have been for years. Hamas does not drop leaflets warning people to evacuate target sites.
The Israelis gave Gaza to the Palestinians, and the Palestinians immediately ruined the infrastructure, chose to put Hamas in charge, and chose to make the Strip an arsenal and launch pad wrapped in civilians.
Tell your friends eyes and ears are important, but so are brains.
