Such incidents can quickly exacerbate tensions between Israel and the Palestinians, including cases in which the IDF opens fire on Palestinians who run Israeli checkpoints. While in this case the settlers ran past a Palestinian patrol, the reason for the ultimate decision by the Palestinian security officers to switch from firing in the air to firing at the vehicles remains unclear.
The incident is largely a test of Palestinian Security Force legitimacy. MK Danny Danon (Likud) has already called for the US to reconsider funding the Palestinian Security Forces, a request he has passed on to Rep. Ileana Ros-Lehtinen (R-FL), Chairperson of the House Foreign Affairs Committee.
To maintain what legitimacy it has, the Palestinian Security Forces will need to not only continue its ongoing inquiry, but follow through. The IDF has an interest in preserving both security cooperation and stability in the West Bank, and will likely play a constructive role in this regard. The Israeli public will want to see arrests, not only inquiries. Given the Palestinian bid for statehood, the Palestinian Security Force's ability to conduct inquiries into its own operations will be a key metric by which the international community may judge its ability to preserve the security of a future Palestine.
