Those weren't graviton hellbores, the BJ's gravitonic nullifiers are field generators that nullify all gravitonic attractions to and from the Jupiter, so that it can actually travel in systems without attracting all local planets, moons and asteroids into orbit. The field was deactivated in one generation sector, and the immediate gravitonic distortions (just though I'd avoid the phrase "gravimetric distortions" as that seems too Star Trek to me, never heard it anywhere else) ripped your ship apart. Your explosives did work, but the explosion was mainly directed outwards, into deep space, as the distortions forced most of the explosives to that section of the ship.

And we can cope with unconventional warfare. I mean, we've got Jack Simth. The guy creates entire pocket universes with a wave of his hand. (Slight note of caution: if you recognise him at a distance, do NOT start waving - the quantumchroniton distortions will most likely tear the planet you're standing on apart)

And moreover, we're attracting entire militaries from other universes. Several hundred thousand Hiigaran Battlecruisers are aready underway, a few dozen fleet of Federation Sovereign-class starships are in orbit reinforcing the few thousand Hiigaran BCs already present, we've got incoming Star Destroyers, Super Star Destroyers, Blockade Runners, Heighliners full of ground forces from the Atreides, Harkonnen, Ordos, Fremen, Tleilaxu, Ix and Sardaukar, there are Asgard ships on their way here, and you can continue forever, right down to the first spaceship Asimov described.
