Could O'Connor have finished the Italians before Rommel arrived, and would Germany still have intervened in Greece without a British threat to its flank?
Short answerO'Connor's prospects remain uncertain in wargames, while German intervention in Greece was still likely.
NotesThe first part remains a genuine wargaming problem rather than a settled historical result. Simulations discussed here divide between outcomes in which O'Connor succeeds and outcomes in which he does not. German intervention in Greece would probably still have happened even without the British move that threatened Germany's flank. Keeping the two Mediterranean counterfactuals separate makes the uncertainty explicit.
