It would be a very nice idea, to be able to leave scorched earth to the opponent, this is an example: "I know that UK want to attack my territory, so I burn the land closest to them, but to burn it (thus demolishing everything and lowering the morale and performance of the territory momentarily) takes 1 day, so I set fire to my land, it takes me 1 day to do it, the general morale of the surrounding towns is lowered, the performance of that town is lowered due to the effect of the morale
