ET exist but are very far from each other, so communication is wining over travel. 1 milion light years or more.

So, you see a SETI attack as primarily useful for intergalactic colonization/expansion? It seems to me that a SETI attack would be an efficient way for a civilization to expand within a galaxy as well. Why do you think it would be useful only at such great distances?
