Interesting, lets put it in another way. We have rats all over the place in almost every corner. Now for example, a rat is sitting in Lahore with US bounty on his head and India loves this rat.
Now US will decide which rat to be taken out, where and when?
Besides, what if a rat takes shelter in a hen's home with 20 innocent chicks around? Are we fine with any sort of collateral damage without any if's or but's?
Finally, the cat you are talking about, I don't want to trust that cat. So my original question still stands there. Cat loves to eat both rat and chicks. What if cat deliberately eat up a few chicks instead of rat and then start calling those chicks as rat? Will we be able to deal with the cat in that sort of situation?
