UNSC = United Nations Security Council
The UNSC was ostensibly created to enforce ‘global peace’ with the first test of the UNSC being considered successful, but decades later it proved to be a covert U.S. operation to control Iran!

The United Nations was originally known as the United Nations Organization, aka UNO.

The ‘western’ push for controlling Iran’s oil reserves actually began during World War Two, at least as early as 1944: New York Times, October 1944; Iran’s oil problem revived by Russia… but Americans also are involved.

From March through April 1946 the newly created UNSC dealt with its first international problem: British controlled Iran demanding Soviet troops to leave Iran’s Azerbaijan Province.
At that time there was no United Nations building, so the first ever UNSC meetings took place at Hunter College in New York:
The problem was resolved by the Soviets ‘voluntarily’ withdrawing troops in May 1946:
Supposedly the true reason for Soviets leaving Iran was that U.S. President Harry Truman threatened to drop atom bombs on the Soviet troops!

This is a political cartoon by Clifford Kennedy Berryman depicting Truman threatening Soviet ambassador Andrei Andreyevich Gromyko.
Decades later, publicly released U.S. Central Intelligence Group (direct predecessor to the Central Intelligence Agency, aka CIA) documents proved the UNSC Iran-Soviet problem to be a covert operation by the United States to expel Soviet troops from Iran for the purpose of allowing U.S. control of Iran and regional oil fields!
80 years later, the game is still being played.
