Consider this too: Hamas could be actually be encouraging militant attacks resulting in Palestinian casualties. Why - because they know full well that Israel must retaliate, instead of just being sitting ducks and appearing weak in the face of their enemies. When Israel strikes back and innocent people die, Hamas actually may want this to occur to further their cause for more sympathy to use as propaganda in the world against the evil Zionist Entity and garner legitimacy. The more violence that they can provoke from the Israelis by attacking them relentlessly the better Hamas looks like a defender.
The danger in this is eventually Israel could strike in all out war.
