During the 1970s and sometimes later, Western and pro-Western governments often supported sometimes fledgling Islamists and Islamist groups that later came to be seen as dangerous enemies. Islamists were considered by Western governments bulwarks against—what were thought to be at the time—more dangerous leftist/communist/nationalist insurgents/opposition, which Islamists were correctly seen as opposing. The US spent billions of dollars to aid the mujahideen Muslim Afghanistan enemies of the Soviet Union, and non-Afghan veterans of the war returned home with their prestige, "experience, ideology, and weapons", and had considerable impact.
