Eight years after his father, George W Bush has begun his term as president of the USA. His father promised us "peace and prosperity" after the disintegration first of the Eastern bloc, then of the USSR. The son inherits a situation of widespread war and poverty, which has proliferated and deepened throughout the 1990s. The state of the world is truly catastrophic, and this is not merely a temporary transition before the promised land prophesied by Bush Senior. All the signs are that capitalism is dragging humanity down into a vicious circle of bloody military conflicts on every continent, of increasing imperialist antagonisms especially between the great powers, a new and brutal aggravation of economic crisis and poverty, and a series of disasters of every kind. These three elements - war, economic decline, and the destruction of the planet - are making conditions ever more intolerable for today's generations, and are endangering the very survival of the generations to come. It is becoming ever clearer that capitalism is leading the human species to extinction.

We know now that the attack on New York has left more than 6,000 dead. Over and above the mere figure - appalling enough in itself - the destruction of the World Trade Centre marks a turning point in history whose full implications we cannot yet measure. It is the first attack on American territory since Pearl Harbour in 1941. The first bombardment of continental America in history. The first bomb attack on a major industrial country since World War II. It is a real act of war, as the media put it. And like all acts of war, it is an abominable crime visited on a defenceless civilian population. As always, the working class was the main victim of this act of war. The cleaners, secretaries, maintenance and office workers who constituted the vast majority of the dead were our people.

The intensification of the US offensive aimed at maintaining its world leadership has led it to unleash a new war in Afghanistan, and to deploy troops there, on the pretext of a world struggle against terrorism. As we will show in the article that follows, this military escalation and its conclusion today in a crushing American victory, far from bringing any kind of stability to the world is, on the contrary, the precursor of new wars and new massacres. Since the article was written, the situation has worsened in the Middle East, which is the object of this brief introduction.

The world has come a long way since the collapse of the bipolar division of the world that characterized the 45-year period of the Cold War. The era of peace, prosperity and democracy that the world bourgeoisie promised with the collapse of the Russian bloc in 1989 has of course never materialized. Indeed the decomposition of capitalist society, which was a consequence of the stalemate in class struggle between the proletariat and the bourgeoisie after two decades of open economic crisis and triggered the collapse of Stalinism, has relentlessly spiraled deeper and deeper into chaos, violence, death and destruction, as humanity is brought closer and closer to a future of barbarism. At the time of the writing of this article, President George W. Bush has just announced that the United States was ready to invade Iraq, with or without international support, even in the face of a failure to get a Security Council sanction for its military action. The breach between Washington and the capitals of major European countries, and even China, on the question of this imminent war is palpable. It is particularly appropriate at this conjuncture to examine the roots of American imperialist policy since the end of World War II, so as to better understand the current situation.

Ten months after a ‘revolution’ which accomplish­ed the great feat of setting up an even more ana­chronistic regime than the one before it, the situation in Iran has forcefully returned to the centre of world affairs, giving rise to a tidal-wave of curses against the ‘barbarism’ of Iranians and Muslims, and of alarmist predictions about the threat of war or economic catastrophe. In the midst of all this noise and furor, so complacently spread around by the mass media, it’s necessary for revolutionaries to look at the
