It has become a familiar chain of events: A Palestinian attack on an Israeli target, is met with what's seen as a grossly disproportionate Israeli response.
A shooting in Tel Aviv on Wednesday took the lives of four Israeli civilians.
Israel responded by imposing sweeping restrictions on Palestinians and revoking 83,000 entry permits, a move the UN says may amount to collective punishment.
What's fuelling the vicious circle? And is anyone interested in stopping it any more?
