The way I see things... Since I was attacked 3v1 and those nations were top 2% the longer I stay in my war, the less tech raiding they can do. Which means the less they grow. Lob a couple CM's their way so they lose a little infra. I will probably bring my troop count to 0 so they can not steal any of my tech. Preventing growth to the top 2% nations is alot better than letting a mediocre nation thrive.
As far as my nation is concerned... There is always next round!
P.S. This is TE everybody tech raids, I guess next round we will just have to tech raid as an alliance instead of each nation picking his own target. No DoW, no warning... just a massive alliance coordinated Tech raid (with peace sent afterwards of course, we are not animals after all)
