I wonder how Breen or Tholia will feel when Romulus is destroyed in 2387 and the Romulans presumably become a burden, not an asset
Martin's latest novel, the one for the MMORPG, suggests that the Hobus supernova was the byproduct of testing of Romulan subspace weapons barred by interstellar treaty. If that's the case, given how drastically things have changed Romulus may survive 2387.
Romulus blowing up is canon - maybe the last canon event to be established about the classic timeline (constructed in Ent, TOS, TNG, DS9, VOY).
There's no chance trek lit will change this. Definitely not by positing that the timeline presented in the trek lit relaunches is not the one from star trek XI.
Might we basically agree on this? Agreed on the declining fortunes of the Romulan Empire, thanks to excessive military spending, and on long-term relative decline, but the Romulan states may have put up a stronger defense in 2381 than their closest great power neighbours, perhaps (my supposition) because of Romulan metaweapons use on top of relatively better military technology, and that the IRS has the best chance of the two Romulan states of pulling out of its downwards spiral?
The romulans could very well have used metaweapons against the borg, putting up a more effective defense than the federation.
This is consistent with their psychology. Also, any weapon tends to be effective against the borg during the first shots - in the case of metaweapons, this would translate into a lot of borg cubes destroyed.
There's something to be said for using superpowered weapons against superpowered opponents.
About the romulans having better military tech than the federation/klingons - that's rather unsupportable.
During DS9's dominion war, the romulan performance was nothing to write home about
During all seen battles, their ships proved to be, at most, at the allies' tech level; no superior anything.
The dominion, even strained as it was by the federation/klingons, managed to keep the 'fresh' romulan military out of cardassian territory, losing only a few recently conquered systems (at most - only one such system is established) before the front line stabilised. During the final battle for Cardassia, the romulan flank broke way before the federation or klingon one.
A highly unimpressive performance, overall.
