Nope, politicians are not military targets. And that makes sense. Nobody would ever talk and try to settle things diplomatically if they could be legally assassinated while doing so.

Also, you can’t have a Nuremberg-style trial with the responsible people if you kill them. The military are following orders and doing what they are told (well, hopefully). The politicians are the ones with the highest responsibility for an invading army. An army serving the state won’t invade unless politicians tell them to.
