I draw your attention to the Lavon Affair, in which in 1954, Israeli operatives planted bombs at American and British facilities in Egypt designed to kill American civilians (it was the U.S. Services Library, and a British Cinema, both full of people) and to blame Egypt. The Israelis did so, hoping that we would then declare war on Egypt and do the dirty work for them. Thankfully, the plot failed.
The Israeli false flag attack was foiled, and it led to the capture and prosecution of several, and the trial and execution of two Israelis, and led to the resignation of the Israeli Defense Secretary, Pinhas Lavon. It is the best-known false flag attack of the Cold War, designed to manipulate the American and British people by murdering our citizens.
So your claim "always" might be overstated.
Also, a while back they crucified the Prince of Peace, which in hindsight, might have been a bad call.
