These figures are worth the paper one which the Oslo Accords were written.
Those under the age of 20, and those who are over the age and have a very selective memory, do not know that Israel shipped to the Palestinian Authority more than 2,000 rifles in the late 1990s, when the IDF was bragging about the coordination between the Israeli military and the PA army, officially called a police force because it is not allowed to have an “army.”
When Arafat could not squeeze more concessions out of Israel, the “policemen” turned their guns on Israel. The rest is history, much of it buried in coffins in Israeli cemeteries.
