It's a frustrating thing to deal with, no doubt, but creating a plan of action when you're pissed off doesn't really lead to a desirable outcome down the road. Is your focus mainly on preserving your population at this point, or getting back at the tribe? Which of those things benefits you the longest? Pain is no fun, but resistance to pain leads to suffering. Your clams will likely suffer (as well as your blood pressure) if you decide to take the spiteful approach.
