Does the weaker British ground-command team still undermine the alternate timeline?
Short answerIt remains a weakness, but Phillips can reorganize responsibilities and bring in a more decisive operational commander.
NotesThe available British ground leadership is imperfect, but time and stronger naval support create options. Percival could be moved toward theater planning, intelligence, and logistics while a newly arrived corps or divisional commander directs field operations. This arrangement uses Percival's detailed knowledge without requiring him to make every fast operational decision. Phillips' presence provides the senior authority and political buffer needed to make that division of labor function.
