I think it may take them a while to realise the power dynamic has changed. They no longer have a say in how we are governed.
It might take some a while to realise that we are a fraction of the EU's trade but they are an enormous part of ours. This means that they have the power in negotiations. No amount of spurious comparisons of us vs individual countries will hide the fact that we need trade with the EU far more than we need trade from them.
