Given that we have a pretty binary choice - the protection of the EU Vs the protection of the USA - Starmer the Remainer is still so frightened of the forces behind, and supporters of, Brexit that he's choosing the option with the unhinged orange lunatic and all the fascism rather than the imperfect but democratically stable cooperative of nations.
