I don't think there will be a third world war. Not over this. However, Russia will be marginalised now and we are going back to a sort of Cold War.
The revolution in Ukraine has weakened Russia and forced it into acting to protect its interests, and this will lead to the exclusion of Russia, which is not something that Russia wanted. The West obviously wants Putin out. They will put an economic squeeze on Russia and hope that a Russian opposition will topple Putin, just like an opposition toppled the Ukrainian President. I don't think it will work because Putin is a nationalist leader and nationalism unites people more than things like Pussy Riot and billionaire funded "charities" and human rights organisations which are used to try and weaken Russia and create opposition to Putin.
I think the revolution was funded and planned and I think the neo-nazis will probably be aided to create trouble for Russia and Muslim terrorists will possibly be set on Russia in order to tie Russia down. I think that all of this will probably distract Russia from what is happening in Syria and that the Jihadis and mercenaries over there will benefit from that.
I agree with Dominic Lawson in the Mail that Russia has been a loser in all of this, and I think that is exactly what the planners had intended.
I think the next part of the plan is to try and topple him through an economic squeeze. I am not sure if that will work. It depends how popular he is in Russia and whether demonstrations will be able to topple him.
' But what is clear is that this has been a desperate defeat for the Russian President.
It is no gain for him to retain the use of Sevastopol — that had always been a given. The bigger picture is that the government in Kiev is, and will be for some time, hostile to Moscow.
Putin’s hopes of tying all Ukraine into a greater Russia — the so-called Eurasian Customs Union — have been dealt a fearful blow.'
...
It will not be military defeat but economics that destroys Putin’s dream: just as it did his beloved Soviet Union.'
