I've been watching the Skylaxians try and take over the Burlust homeworld since...oh when they became spacefaring (you know, like five years into the game and its now 3030).
The Burlusts have 0 armada defending their planet with 639 attacking armadas with a combined strength of 213,338. Population has only dropped below double-digit millions in the last few moments (I haven't been watching it, when they started their attack at 10k strength the Burlusts had 280M pop and it would GO UP, peaked around 310, and last I checked--about 3 in-game years ago--it was still over 100M).
Oh, and I can't bomb the planet's surface myself, because I can neither aid nor go-it-alone against the Burlust armadas....because they have none.
