Aggressive warfare is still illegal, like bank fraud, or murder. I agree there is a problem with enforcement, rather like white collar crime, or child sex abuse. The UN is not much help. The silly thing is if you don't pay your TV Licence, or Council tax, you are in the clink in no time at all.
It's like Hillary Clinton saying in the past that she approves of narcotics because there is a demand for it and it improves the administrative corruption of the GDP figures.
There were some stupid journalists on Sky TV the other day saying that the EU had protected Europe from Russian aggression and terrorism. If those journalists had any military or security experience, or wide and practical experience, they would understand that Russia has been restrained by NATO, and by our armed forces. How many divisions has the Vatican got?
I think it was financially sensible for the UK government not to join the Euro currency. We might have ended up like Greece.
In any case Russia only has an argument at the moment with Turkey for shooting down one of its warplanes, and with the fascist beasts in the Ukraine, and the right-wing lunatics in America.
