The fastest way to stop the killing and ethnic cleansing of palastinians is for them to disarm, surrender and accept israeli/american peace terms.
The best and fastest way to get palestinians to do that is to stop cuddeling them, stop the subseides and international aid and stop incentives them to remain stateless and without responsibility.
The best way to that is disturb the balance of power where the arb world and western people keep feeding thier delusion of grandure where this conflict end in any other way then them keep losing land and lives.
They will not have a state on thier terms, but ours.
They have lost and it's time for the world to let or force them accept it and not delude them further.
The main problem is the world allowing palestinians to continue playing stupid games and win stupid prizes. The main problem is giving them false hope by marching on some streets chanting free Palestine.
The notion that Israel enjoy killing palestinians civilians like it's a sport is part of a 20 years arab/russian propaganda campign of dehumanizing Israelis and jews.
