All the seven mistakes appear to be accurate and in the aggregate lead to the vote for Brexit but the greater stupidity has been since the vote. It has been and is the stupidity to think a legislative body like Parliament could come to an agreement on something as specific as “executing Brexit”. Legislative bodies like Parliament and the U.S. Congress must be lead. They react. They can say yes or no and sometimes they get away with maybe, like the U.S. Congress after President Lincoln’s emancipation proclamation, but they never, never propose. In addition they react best to leaders who offer vague and often amorphous proposals on which legislators can claim they votes both yes and no.
But and it’s the big “But”, leading a legislative body is not the same as saying “leaders propose, legislators dispose”. It’s working the halls and offices, meeting with individual legislators to “create” a solution on which 51% of the body can agree. This is what Tip O’Neill in the U.S. and Winston Churchill in the U.K. did like they were creating a Pablo Picasso abstract. This is what Theresa May never did. She spent more time in Brussels than she did in london and that is the real “stupidity” of the failure to implement Brexit. But, it may have been a brilliant success instead of a stupid failure. 🤷♂️
