I think that the real thing we must deal with here and now is Ukraine. We must make sure that Ukrainian people have the ability to defend themselves should the Russians overstep the mark.
The long-term solution is of course through economics. It is important to resolve the EU-US free trade treaty to make Mr Putin feel what isolation is like, and to help Europe come to terms with its apparent energy dependency on Russia, which only makes it more and more vulnerable to a man who has proved time and again that he uses energy as a weapon.
There does not always have to be a hot war or a high -stakes conflict for us to face each other down. How quickly we rushed to forget the lessons of the cold war and sought to retire members of the intelligence agencies who were put out to grass when it ended in 1990-91. Let us remember that intelligence agencies around the world helped to change the behaviour of the Soviet Union and to make it collapse from within. Not a month now goes by without people denigrating our intelligence community —most recently thanks to Mr Snowden, who is now enjoying the hospitality of Mr Putin, and there is an irony in that—but they largely understand the Russian bear, know what makes Mr Putin vulnerable and know how to turn up the heat.
Let us remember that the source of Mr Putin’s power is the secret state, in which he can imprison people without trial, and in which he can persecute homosexuals and non-governmental organisations in the Russian state. He gets his power from manipulation, intimidation and corruption, but that is where he is vulnerable. If we can deter and deny him the ability to use that state within Russia and further afield, we can weaken him, and in doing so we can certainly deter him in future.
Let us unleash our intelligence services and capability. Let us no longer be afraid to hide them and run away from the accusations of Snowden. Let us make life a little more uncomfortable for Mr Putin. Let him feel what it is like on the other end of his intimidation in the secret state. Let us not put him in a cold war, but let him feel the cold winds of isolation that we can bring about if we isolate him economically, isolate him militarily and isolate him in his ability to break international law around the world. One cannot be a major player, riding bareback on a horse, if one is isolated from the international stage.
