This strategy works great if your counterpart knows you're employing it.... The worrying thing about this is that Boris apparently thinks his/May's current approach is sane.
The concession the UK wants (full access while not crossing May's red lines) is impossible. I can't see any other concession that would satisfy the UK's needs, the red lines will need to disappear.
Exactly, I feel that people still don't clearly understand that the concessions demanded from the EU are literally to sign a FTA and Custom agreement with the UK while the UK keep total independence from the other 27 countries, not only it makes no sense from a political or trading standpoint but it's also a huge problem from a legal POV.
The legal problems are particularly important here because we have the fresh example of the GFA, a deal built around a context(EU membership) that could have been unilaterally altered and made inapplicable. That's something that you don't want, that's why jurist and contract managers are crucial, you can't let or create obvious holes without clearly addressing them and the problem here is that not every holes can be filled, for example it's not possible to have two trade agreements in one custom and trade territory that contradict each others without having a common jurisdiction that will impose the rules on everyone.
