Hybrid Wars (PDF)
In light of the Charlottesville attack, I'm sharing this PDF on hybrid warfare, which is what Russia and the United States are indirectly doing against one another.

It's a rather philosophical book, but it offers an introduction into modern state-sponsored revolutions. Among other things, the book advocates the usage of modern technology to accomplish geopolitical goals. Hybrid Wars also discussed many relevant theories, forms of revolutions, methods of unconventional warfare, etc.

I'm sharing this PDF because of its relevance. It's not meant to display camps of good and evil, just be aware that the governments in Moscow and Washington adhere to the principles of hybrid warfare.
