"Reactionary terror isn’t an understandable response by the toilers to imperialist aggression"

This is the crucial point, and I've never seen it more clearly formulated:

....In a May 29 interview on Legacy Radio, Clifford took up Corbyn's claim that the growth of Islamic State and its terror attacks are a blow-back from London's participation in the Washington-led Middle East and Afghanistan wars.

Reactionary terror isn't an understandable response by the toilers to imperialist aggression. The Algerian people faced tremendous brutality at the hands of French colonialism, but they didn't respond in a reactionary anti-working-class IS-style way, Clifford said. "They organized a powerful revolutionary struggle and established a workers and farmers government."

And in Cuba, Fidel Castro and the July 26 Movement led workers and farmers to overthrow the U.S.-backed Fulgencio Batista dictatorship. They have defended their socialist revolution for over 50 years, setting an example for workers everywhere.

Working people in the Middle East don't need U.N.-imposed "stability," as Corbyn has argued, Clifford said. They need time and space, free of foreign intervention, to find the way to fight for political power. "The Communist League calls for U.K., U.S. and all foreign troops out."
