first one that comes to mind is Operation Cyclone - he armed the reactionary mujahideen in afghanistan to impede the USSR's support of the nascent Democratic Republic of Afghanistan

He armed Indonesia during their genocide against East Timor.

Unfortunately, despite its professions of support for human rights in Indonesia, the Carter Administration picked up where Kissinger and Ford had left off. As Noam Chomsky writes in the preface to Matthew Jardine's 1995 book, East Timor: Genocide in Paradise, "In 1977, Indonesia found itself short of weapons, an indication of the scale of its attack. The Carter administration accelerated the arms flow."[7] U.S. arms sales hit $112 million in 1978, and averaged nearly $60 million per year for the four years of the Carter administration -- this was more than twice the level of weaponry supplied to the Suharto regime by the Ford Administration.

Reagan and the wave of conservative world leaders in the 80s made it the new status quo, but Jimmy Carter is often credited as the first neoliberal president and the starting point of neoliberalism in the US.

Here’s a short write-up: https://afflictthecomfortable.org/2020/11/19/jimmy-carter-is-a-saint-now-was-a-war-criminal-then/

Fudge the iran hostage crisis, operation cyclone, partake in east timor genocide.

He walked so reagan can run

The father of neoliberalism in the US lol. Many people think it’s Reagan, but Carter laid the groundwork for everything that happened afterwards.

He kinda did the Khmer rouge so jot that one down. Also the mujahideen. Sold peanuts too, prick.
