Lets think about this logically. The Zurg have mastered interplanetary space travel to the point where they can send a large fleet to another planet. If we had such power would we help others in our position. When you walk to work or school or whatever and you pass an ant hill do you stop and go down to them and say "here is cold fusion, and advanced weaponry all gifts to you"? No, you walk right on by, maybe step on a few as you go. The Zurg are not here to help, there is nothing in it for them. OPEN YOUR EYES!!!
