Several Palestinians have killed Israelis in the street using cars or knives. It is not exactly suicide, but some of them have been killed. The prospect of death or imprisonment has ceased to deter Palestinians from getting revenge for the occupation.

Killing civilians who are doing nothing wrong is not justified, and the responsibility falls on Netanyahu as well as the Palestinians who actually do it.

Netanyahu threatens more collective punishment against Arabs in general — just the thing to inspire this violence to grow.

I suppose Netanyahu finds this violence a convenient distraction to enable him to continue stealing land and water.
