There won't be W.W. III Read, Pause, and Reflect!!! The capitalists do not wage war for patriotism, democracy, or any other high-sounding principles. They wage war for profit, to capture foreign markets, sources of raw material (such as oil), and to expand spheres of influence. Is that elementary proposition not absolutely clear? And is it also not quite clear that a nuclear war would signify none of these things, but only the mutual destruction of both sides. They have even coined a phrase to describe this: MAD (Mutually Assured Destruction). That such a war would not be in the interests of the bankers and capitalists will be evident even to a not very intelligent child of six, although apparently it is not evident to some people who, for reasons best known to themselves, call themselves Marxists. Another decisive factor is the mass opposition to war, particularly (but not exclusively) in the United States of America. A recent poll indicates that only 25 percent of the US population would favour direct military intervention in Ukraine, which means that the overwhelming majority would be opposed. This is hardly surprising, given the humiliating defeats suffered in Iraq and Afghanistan, a fact that is burned in the consciousness of the people of the United States. That was already shown when Obama attempted – and failed – to get permission to intervene militarily in Syria. The people of the US are heartily sick of foreign interventions and wars, and this is a powerful factor limiting the room for maneuver of both Biden and the Pentagon. It is this, and not any fear of the Third World War, that has prevented them from sending troops into a direct confrontation with the Russian army in Ukraine. http://www.marxist.com/the-ukrainian-conflict-is-this-the-start-of-world-war-iii.htm
Last 4 paragraphs are ok. The rest is lost in petty abstraction. There is no simple reason for any war.
