President Donald Trump announced on Thursday that the United States will withdraw from the Paris accord. After a fraught meeting with the other G7 countries, he unilaterally withdrew from the accords. This marks a decisive turning point in world relations, and shows the inability of capitalism to create a sustainable future for humanity on this planet.

For the comrades of the International Marxist Tendency, Marxism is the historical memory of the working class. In its struggle with the bourgeoisie, the victories, defeats, traditions, and hopes of the workers are distilled and synthesized into a revolutionary theory of action. This “unbroken thread” extends back in time, an uninterrupted line of thought beginning with Marx and Engels, developed further by Lenin and Trotsky, and taken into the modern epoch by those who have worked for world revolution since Trotsky’s death.
