Here's why to worry that Hamas-Israel violence may erupt again

Expect an escalation of new violence between Hamas, other terrorist groups, and Israel in the coming days.

The spark that has lit the fuse is Hamas’ continuing harassment of Israeli settlements just outside Gaza. Hamas is employing the ingenious but indiscriminate tactic of launching incendiary kites into Israeli forests and fields. It’s ingenious because the international media views the kite attacks as harmless (even though they damage Israeli property and risk lives). But on Monday, Israeli Prime Minister Benjamin Netanyahu responded by closing a key border crossing that facilitates Palestinian trade with Israel and Egypt, and by limiting how far off-shore Gazans are allowed to fish.
