I think Israel has to learn from Europes suffering.
There are certain groups of people, who can terrorize a whole nation. It even needs for this not milliones of them.
If I would be responsible, I would explore the record of certain cultural groups in other civilized countries. Based on this I would expell the people that endangers society. Looks like a collective punishment, but really it is not, because legally all have to leave. So such kind of method is in fact a clemency. The people who are allowed to stay should assimilate and this driven by their own will.
For one group, there is no need for exploration: Muslimes of all colors. They have to be deported instantly no matter what the situation in their homeland is. This people are a cancer and a life threat for everybody. It is hard hearted to allow this dangerous animals in your society. Muslimes are cowards. They attack the weak and the elderly first and the gouvernment has an extra responsibility to protect the weak. God told us so.
