Hold on there ^^^
I get your point, but in ST fictional context...
For argument's sake, say the Enterprise had the invasive virus weapon ready to unleash at the last moment of BOBW, with the Earth on the verge of assimilation.
It would literally be...use the invasive program, wipe out the Borg genocidally -OR- the Earth is assimilated, followed by the rest of the UFP.
Riker should have declined, it is wrong to commit genocide.
Enterprise stands aside as the Borg cube begins assimilation.
Is that what you're claiming? THAT would have been the correct course of action?
(All fictional, I know)
Well, see, now (IMHO) you're talking about two different things.
In the case of Picard it was a "less active" war situation. At that point the Federation was pretty much in a "cold war" with the Borg. The Federation had defeated the one ship sent to attack Earth and after that point the Borg had done nothing else to the Federation.
For all intents and purposes they were "even" in the war which had gone cold.
If Picard had implemented the program the war would've gone hot again and, since it's unlikely it would've wiped out all Borg, it would've likely just prompted them to step-up their efforts to assimilate the Federation. The retaliation from the Borg may have been something that couldn't of been stopped.
