Re my comment on “make sure the steps we have taken are ones we can lock down and not be subjected to undoing through [Congress] or otherwise” yesterday. The sure way that steps cannot be subjected to ‘undoing’ would be for the President to issue his own amendments to the Constitution. I bet he is really thinking about how he can issue a constitutional amendment via executive order. One catch: if he can do it, then future president could rescind under same lame reasoning. Maybe there will have to be some sort of legal “no tagbacks” language, whatever that would be. Or the word “perpetuity” in the amendment might help.
