Family incitement is suggested in the latest case. Close relatives of the young killer were also murderers, and their treatment by Israeli authorities became one of the reasons leading to this killing.
Responsibility and cure are topics that are hard to pin down.
What we hear from the left is that a peace agreement may be the best way to lessen Palestinian violence, but few if any are claiming that peace will end it entirely. Among the elements that provoke it are religious doctrines that anyone who is not a Muslim has no rights in the area, and certainly no right to rule over Muslims.
Religious scholars and left of center political activists will argue that such a view is a distortion of Islam. However, such claims do not prevent individual preachers--with or without education and official designation as preachers--or individual family members from passing on their hatreds of Jews, justified by religious-sounding mumbo jumbo.
Should not any discussions of peace, and certainly any formal agreement insist on reforms that reach into schools, media, and mosques?
It has already been done, included in agreements signed by Palestinians, Israelis, and Americans.
Israeli officials need not demand that Palestinian children sing Hatikva before every morning lesson, but maps in school books showing Israel and a lack of "Jews are apes and dogs" from the media and mosques should be an elementary demand for beginning any negotiations.
Palestinians have said that they cannot end freedom of expression.
Hah! Palestinians do not honor individual rights more than any other Third World kleptocracy.
USAID, equivalent bodies of the European Union, as well as NGOs concerned with human rights can finance a new edition of Palestinian school books with maps showing that Israel exists, and demand the restraint of excessively nationalistic teachers, school principals, media personnel and mullahs.
Jews also should enjoy human rights.
The Palestinians can deal with any who continue with the hateful themes by dropping them from the roof of Ramallah''s tallest building, in the manner of how Hamas has dealt with those who resist its rule in Gaza.
Israel must admit to its own problem of individual violence.
The latest incident was the night-time burning of a Palestinian home in the outskirts of Ramallah. Thanks to an alert mother, two children escaped with their lives before the total destruction.
Israeli security forces claim to be frustrated in identifying those responsible, perhaps loosely allied, and said to be under the guidance of charismatic rabbis.
A fair comparison of violence and the efforts of police would find Israel scoring higher on measures of civilization than Palestine. However, the differences are not absolute. Israel is a lighter shade of gray. It''s hard to escape the conclusion that some well placed Israelis view Price Tag as giving an appropriate message to Palestinians about the costs of their own violence.
The Obama administration has been as responsible as anyone else for the recent increase in violence. Its obsession with forcing Israelis and Palestinians to a table falls into the category of making things worse. Participants in the talks appear to be doing nothing more than accusing one another of preventing any accomplishment.
Such a message filters out to the street, and contributes to whatever other incitement provokes individuals to take up a knife, throw stones at a passing car that looks Jewish, or make a fire bomb.
John Kerry''s warning that Israeli stubbornness will contribute to a third intifada deserves special attention. Whoever gives licenses to diplomats should remove his.
