An interesting piece of information...

It seems the Americans put quite a bit of pressure on the Israelis. Did they do the same with the Palestinians?

The US imposed a sales embargo on spare parts for helicopters during the first year of the Intifada, former head of the Shin Bet, Avi Dichter, revealed on Thursday.

In a speech at the Saban Center for Middle East Studies at the Brookings Institution, where Dichter is now a fellow, he said that the embargo was short-term, and was imposed because the of the Israeli policy of "targeted killings" by the Israeli air-force using US made helicopters. "The embargo was lifted after the 9/11 attacks", Dichter said in his speech.

This is the first time an Israeli official has mentioned such an embargo on military equipment, and it is not clear what spare parts were banned for sale to Israel
