The most interesting - in fact, inspiring - people I met there [Porto Alegre] are those who remain nameless: representatives of the international campesino movement, the East Timorese delegation,... - the usual heroes, who disappear, unknown, apart from the consequences of their work.

[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.

I think it's just been a core part of the Cuban revolution to have a very high level of internationalism. I mean, these cases you've mentioned are cases in point, but the most extreme case was the liberation of Africa. Take the case of Angola for example, and there are real connections between Cuba and Angola-much of the Cuban population comes from Angola.

The people who were really important are the ones whose names are forgotten. And that's true of every movement that ever existed.

Over the years, there's been case after case when there were very narrow decisions that had to be made about whether to launch nuclear weapons in serious cases. What is this guy [Donald Trump] going to do if his vaunted negotiating skills fail, if somebody doesn't do what he says? Is he going to say, "Okay we'll nuke them? We're done?"

Most of us who were opposed to the war, especially in the early '60's - the war we were opposed to was the war on South Vietnam which destroyed South Vietnam's rural society. The South was devastated. But now anyone who opposed this atrocity is regarded as having defended North Vietnam. And that's part of the effort to present the war as if it were a war between South Vietnam and North Vietnam with the United States helping the South. Of course it's fabrication. But it's "official truth" now.

Suppose that the US really is trying to get rid of drugs in Colombia. Does Colombia then have the right to fumigate tobacco farms in Kentucky? They are producing a lethal substance far more dangerous than cocaine. More Colombians die from tobacco-related illnesses than Americans die from cocaine. Of course, Colombia has no right to do that.
