I am not a pacifist: I think that fighting PISSI is legitimate provided it is done in ways that don't tend to cause lots of civilian casualties. I don't trust the US government to limit itself to those ways.

Clinton is not likely to do anything to restrain the increase.

Trump says he will do so, but what such a liar says means little.
