What have those aggressive Zionists done to make this poor palestinian girl cry?

That’s right. She’s mourning her relative – an Islamic Jihad terrorist dedicated to the murder of innocents and ultimately the destruction of Israel.
What the caption does not tell you is that we hit the terrorists as they were trying to launch a rocket or mortar at Israel, despite the caption’s claim of a commitment to calm.
Taking out the terrorists will not prompt anything except perhaps the cowards thinking twice before firing rockets again, and residents of Israel resting a bit easier for a little longer.
This was no tit-for-tat. This is a matter of taking out those trying to kill us.
