The Jimmy Carter regime was responsible for encouraging the growth of a violent form of a far-right movement that has caused huge suffering in the world: Islamism.
A military coup in Afghanistan in April 1978 established a left-wing regime that was committed to implementing reforms that had been implemented in other countries as feudalist systems were overthrown. There was land reform, and women were given rights The landlords and the moneylenders and the imams were unhappy about these reforms and launched an armed rebellion. The new regime was allied to the USSR, with which Afghan state had long had friendly relations.
The Carter regime decided to give support to these rebels, with a view to provoking the USSR to intervene to prevent the establishment of a potentially hostile regime on its borders. This would be a drain on the USSR, both economically and militarily, which would be to the advantage of the interests of US imperialism.
Sure enough, the USSR sent troops into Afghanistan to bolster the Afghan army in December 1979.
Then the Carter regime gave even more aid to the Islamist rebels in Afghanistan.
The war in Afghanistan became a cause célèbre of Islamism, and the USA encouraged the governments of predominantly Muslim country to free Islamist dissidents and allow them to travel to Afghanistan to “fight the Godless communists”. This led to the birth of Al Qaeda.
Thus the Carter regime helped set the world on a road that led to the civil war in Algeria, the destruction of the Twin Towers, the enslavement of Yazidi women, and all the other horrors inflicted in the past forty-six years by violent Islamism.
