Intensifying Interimperialist Contradictions contains Jose Maria Sison's writings from 1989 to 2021 on the economic, political and military interactions among imperialist powers as they rise and decline and how these could develop and lead to interimperialist world wars, such as World War I and World War II. But the proletariat and people of the world are waging anti-imperialist and democratic mass struggles in the imperialist countries and on a global scale. There are revolutionary armed struggles persevering in a number of underdeveloped countries. All these are the prelude to the resurgence of the world proletarian-socialist revolution.
