Food, medicine and water is blockaded? sure. Go on a mass hunger strike. Let the world know about it, inform them about your suffering. I guess that has already started to some extent too. Forced into a apartheid set up on your land, forced to go through humiliating check points? March peacefully with full restraint to the check point. Don't get violent no matter what. Show the world what's happening there.
This is far better than the rocket attacks.
