Well!, I really believe, honestly, at this rate, it will definitely, take another ten years or more, just for all of them to purposefully negotiate, possibly a slightly 'better trade agreement' while, everyone would keep pretending, it's such a huge victory.
Though Brexit, started with much hullabaloo and its repercussions later to be dealt with.
It's a personal opinion though, there is no harm in accepting, leaving EU was a mistake and it needs to be corrected.
