Quote: American history is littered with examples of military intervention and political meddling in the affairs of foreign countries. There was the US-backed overthrow of Iran’s democratically elected leader in 1953; the 1954 coup in Guatemala engineered by the Central Intelligence Agency; US funding of brutal “dirty wars” against leftists throughout Latin America in the 1970s; and much more.
The post-9/11 era is no different, though the methods of warfare have changed. US military intervention in countries like Yemen have destabilized nations and killed innocent civilians in the name of the “war on terror.” The current crop of undeclared wars the US is waging is having a deleterious impact around the world. And there’s also the so-called war on drugs, which the US continues to wage despite devastating consequences on the ground.
