Hamas has been raining rockets on Israel now for a couple of weeks. Several a day.
This morning, Israel had enough. They're hammering Hamas targets. Of course, Hamas lives among the population. They use backyards to launch rockets. They're terrorists of the worst stripe.
Expect civilian casualties. Hamas uses the population as shields and as propaganda fodder. Hamas wants civilian casualties, so they do everything they can to cause them. And frankly, the residents of Gaza have only themselves to blame. They allow it. If you let your backyard be used as a rocket launching site, you shouldn't complain when Israel bombs your house into rubble. That's common sense.
The people of Gaza are bereft of common sense.
