It has no real bearing, but it does provide us with a view of what is going on behind the scenes in the tunnels of power in Brussels. Remember that Britain is planning on a referendum to stay or leave the EU, not join the Euro. That is highly unlikely to ever happen, and after recent events I think it is absolutely clear that the ECB cannot be trusted not to use the Euro as a weapon of mass economic destruction.
I was a vehement believer in the concept of a united Europe. In some ways I still am, but only with regards to the base concepts of freedom of movement and freedom to work.
I am British and I have taken advantage of the freedom of movement. I have lived in several countries in the EU. I haven't returned to the UK since 2004. That freedom is incredible, and I hope it doesn't change.
The Euro though is a different matter. It is dividing the EU. It is creating the have's and have not's. It is being used as an economic nuclear weapon in order to force the will of one nations economic culture and expectations on to others.
Greece made a mistake back in 2010. At that point they should have embraced the Grexit. They should have crashed and taken all the German and French banks with them. Now the foreign banks have no risk in Greece. The ECB has bought them all out and the ECB and IMF hold the Greek nation by the balls.
If I was Greece I would implore Tsipras to follow Varoufakis' plan. It might not work, but it might just work, and I guarantee that another bail out is not going to change a damn thing, but move the current shit storm into a larger shit storm three years down the line.
