Your's would just aspolode when you look at them the wrong way. 
You mean...lasciviously?
Also, all y'all are crazy. There's an easy and obvious way to take down those pesky Sathani: relativistic kill vehicle impacts.
Sure, you usually use subspace for long-distance travel -- but why not build a powerful fusion torch instead, stick it on a heavy penetrator, station a few in every system, and wait? When you spot one of those big clumsy Sathani coming in from a neighboring system, ignite the RKV's drive, accelerate it up to some ludicrous percentage of lightspeed, and time it to arrive at the node just as the Sathanas is emerging.
Boom! The RKV whaps into the Sathanas with
much more kinetic energy than any piece of drifting debris. It's going so incredibly fast by Freespace standards that there's no real chance of intercepting it or slowing it down -- and even if you did, the debris cloud would still do the job.
Now, to be fair, it has a couple weaknesses: the Shivans might see it coming if they have a superluminal sensor system, or they might make another subspace jump before the RKV could arrive.
But still, if it worked, cheap and reliable way to take them down.
