We need an option to disobey the treaty and shoot them anyway. Of course, the other empire will probably get very angry and declare war.

I disagree. You just have to break the treaty and then you can do what you want. Eveything else leads to the same diplomatic inconsistency we still have in many other aspects: The empire A demands that you attack empire B and you accept the demand but do nothing. Still empire A is very happy that your "honour your obligations"!
