The 1 borgone Borg cube they sent to earth was enough to surely defeateddefeat the armada. The only reason borgthe Borg ship was destroyed was because captain picardCaptain Picard’s interference.
picardPicard was assimilated by the borgBorg therefore the borgBorg gained alota lot of experience about the federationFederation which resulted wolf 359 but when picardPicard’s humanity returned and he was no longer borga Borg drone we had alota lot experience about them which there was alota lot from the collectiveCollective hive mind this. This gave picardPicard the advantage to knowof knowing weaknesses against borgthe Borg cube if picard. If Picard did not aid the federationFederation armada against the borgBorg heading to earth federation, the Federation would have been swiftly defeated.
The borgBorg objective is to assimilatedassimilate anything worthy for assimilation and improve borg technologyBorg technology; therefore most entire borgBorg cubes across the galaxies are assimilating species,they also are defending there own space and above all protect queen complex but for those little confused by that can refer to it as borgBorg capital which you can see protected by borgBorg cubes on one the voyager series
sendingSending more than one borgBorg cube willwould logically be a waste of resources,overkill and borgresources—overkill—and the Borg are overconfident that they will succeed in assimilation and as can imaginebe imagined they can spare borgBorg cube to it be very meaningless to the queen unless losing more than one cube purhapsperhaps, and as matter of fact borgthe Borg cube wouldntwouldn’t have failed if wasnt for picardPicard’s knowledge of the borgBorg, which we used against them just as they used knowledge they assimilated from him.
