The Modus operandi of modern imperialism is based on the principle of Exitus Acta Probat, Latin for the end justifies the means. Imperialism and Capitalism are two sides of the same coin. It can be said that without colonialism there can never be imperialism, and, subsequently, no capitalism. The main proponent of Capitalism is the British-American Alliance, and the instrument of that power is the Dollar.
The World Capitalist System is in severe crisis because of negative energy flow, that is, the extraction of wealth from the rest of the world is decreasing, while the energy needed to maintain the viability of the Anglo-American System is increasing. That is not sustainable.
The Anglo-American leadership is convinced that, if it took control of the regions of the former Soviet Union and the natural wealth of that area, it would be in control of the world for the next several centuries. As a result, the confrontation with Russia is inevitable. Only time will tell.
