Saudi Arabia only consented to the embargo after Nixon's promise of $2.2 billion in military aid to Israel. The embargo was accompanied by gradual monthly production cuts—by December, production had been cut to 25% of September levels.
In 1973, Nixon named William E. Simon as the first Administrator of the Federal Energy Office, a short-term organization created to coordinate the response to the embargo. Simon allocated states the same amount of domestic oil for 1974 that each had consumed in 1972, which worked for states whose populations were not increasing.
In 1973, Carlos conducted a failed PFLP assassination attempt on Joseph Sieff, a Jewish businessman and vice president of the British Zionist Federation. On 30 December, Carlos called on Sieff's home on Queen's Grove in St John's Wood and ordered the maid to take him to Sieff. Finding Sieff in the bathroom, in his bath, Carlos fired one bullet at Sieff from his Tokarev 7.62mm pistol, which bounced off Sieff just between his nose and upper lip and knocked him unconscious; the gun then jammed and Carlos fled.
