Iran was a democracy when it nationalized its oil in 1953
Great Britain had developed (and profited from) Iran's oil industry, then was cut out much like what Venezuela did. Britain hit Iran with sanctions which the USA joined, then Iran connected with the Soviet Union to rescue its economy. This was during the Cold War, so we conspired with Britain to support a coup that deposed Iran's democratic government, installing the autocratic repressive rule of the Shah.
Twenty five years later, the Iranian people rose up and kicked him out, following religious leader Ayatollah Khomeini in the Islamic Revolution.
That regime is still in power, an avowed enemy of the "Great Satan" America.
Unintended consequences are often the result when greed and hubris supercede our ostensible principles. We helped destroy a democracy, and spawned a theocracy antithetical to our national interests.
But NONE of that history comes close to matching the hubris, greed, incompetence, and sheer mendacity of the Trump administration.
We're racing at breakneck speed to transform America from the Shining City on the Hill (always more of an ideal than a reality) to the Late Great United States.
For any lurking Magats:
That means America will no longer be great, as a direct result of what your cult leader has done and is doing.
