[Donald] Trump has been very inconsistent on many things; on Twitter he's been all over the place, but some of it is very consistent. That is: Do nothing about climate change except make it worse. And he's not just speaking for himself, but for the whole Republican Party, the whole leadership. It's already had impact, it will have worse impact.

Every predecessor has used mercenaries, often drawn from the country that they're attacking like England ran India with Indian mercenaries. You take them from one place and send them to kill people in the other place. That's the standard way to run imperial wars.

The most dramatic case is that of the Central Americans. Why are people fleeing Central America? It's because of the atrocities the U.S. committed there. Take Boston, where there's a fairly large Mayan population. These people are fleeing from the highlands of Guatemala, where there was virtual genocide in the early 1980s backed by Ronald Reagan. The region was devastated, and people are still fleeing to this day, yet they're sent back.

This crazy ban on the seven states, where we can't accept immigrants, almost every analyst points out the obvious: It just increases the threat of terror. It lays the basis for terror. It's just like the atrocities in Abu Ghraib and Bagram and Guantanamo. They're the most fabulous recruiting techniques for Al Qaeda and ISIS.

In fact, the Outer Space Treaty of 1967 bans militarization. Potential adversaries of the US, and even its allies, are so far behind that these countries are very interested in maintaining the treaty. Europe and the rest of the world want a strong reaffirmation of the Treaty and the US is unilaterally trying to derail it. Termination of the treaty would mean that the US could develop satellite weapons, put offensive weapons in space. It would probably mean using nuclear power in space. All of this leads to some very dangerous scenarios, including destruction of the species.

...free enterprise, [is] a term that refers, in practice, to a system of public subsidy and private profit, with massive government intervention in the economy to maintain a welfare state for the rich.

A fundamental element of human nature is the need for creative work, for creative inquiry, for free creation without the arbitrary limiting effects of coercive institutions. A decent society should maximize the possibilities for this fundamental human characteristic to be realized.
