What was the invasion of South Vietnam, for example, in 1962, when Kennedy sent the Air Force to bomb South Vietnam and start chemical warfare? That's aggression.

Independent development can be a virus that can infect others.

Latin America is all moving to the left, from Venezuela to Argentina with rare exceptions, but there's a good left and a bad left.

In other countries, rich and poor, education remains substantially free, with educational standards that rank high in global comparisons. Even in the US, higher education was almost free during the economically successful years before the neoliberal reaction - and it was a much poorer country then. The GI bill provided free education to huge numbers of people - white men overwhelmingly - who would probably never have gone to college, a great benefit to them personally and to the whole society. Tuition at private colleges was far below today's exorbitant costs.

I am not sure just what Marx had in mind when he wrote that "philosophers have hitherto only interpreted the world in various ways; the point is to change it." Did he mean that philosophy could change the world, or that philosophers should turn to the higher priority of changing the world? If the former, then he presumably meant philosophy in a broad sense of the term, including analysis of the social order and ideas about why it should be changed, and how. In that broad sense, philosophy can play a role, indeed an essential role, in changing the world.

The "end of history" has been proclaimed many times, always falsely.
