Offering "face saving" to Johnson --in exchange for ratification of the EU Withdrawal Agreement or, especially, restoration of unqualified EU membership by the act of A.50 revocation-- confounds (1) terms of agreement and (2) commitment to membership as peer.

What "face" of UK gov merits saving anyway?
The exceptional industry of the people with respect to all others appears uncontested. Perhaps you have found some indication that they fear for anyone but themselves.

Observers the world over of BREXIT pilgrims recognize in  tory progress toward sovereignty a concomitant reluctance to clip imperial ambition. Perhaps the attitude of moral superiority with which UK delegates approach members is no affront but welcome aspect in society. Surely the niggardly disposition of UK gov toward its "homeland" constituencies, dependencies, protectorates, and Overseas Territories expresses common courtesy. Conversely, appreciation for dishonesty in discourse will perfect the status of everyone.

Tell us how corespondents of tory government should ease regrets and transgressions of figures, known and unknown, who are demonstrably incapable of accepting responsibility for and responsibility to much less forgiveness?
