Not to beat a dead horse, but does the Earth/Romulan conflict had to be a space war? The conflict could've been set on a planet, like a conventional war, and vessels not as complex as TOS ships were sent to bring supplies and weapons. Just imagine there were a series of conflicts or battles in not just one planet but multiple planets between the Romulans, Earth, and the Vulcans, I think this scenario would be a satisfying event than another series desperately failing to ape off Star Wars. Whatever the outcome, the Romulans stayed off the map for a century and their ships and weapons were not up to date like a Starship and their vessels lacked defensive screens and indulge in a stealth process. Basically, after this war the Romulans suffered from an economic and technological collapse; rebuilding their foundation as time pass by. So I don't believe the Romulans had a cloaking device during that War, and had to use unconventional means to re-invent what was lost. Casualties of War. Earth and the Vulcans continued to prosper as the Romulans licked their wounds and hibernated until they could threaten the Galaxy again.
