Who is blaming anyone? Both sides are trying to do what they see as their best interests. That is as it should be: no blame is attached.

That we are less successful is partly because we are unable comprehend that trade is not the sole interest of the EU, which is why we get this nonsense about the EU going against a deal that is in their own interests. They are not, they just have a wider view of what is in their interest than just trade.
