So let me just understand your position here. Suppose the US declares war on Venezuela. Suppose a venezuelan living in America just looks up a bunch of US generals addresses online, and then sets all their houses on fire killing them in their sleep in their McMansions in suburbia.

Are you saying that's a valid military strike, and therefore can't possibly be terrorism? Suppose this person is so successful he kills 1,000 and generals and numerous quit their jobs and move in fear for their life, just to really clarify what you're arguing here.

The Geneva Convention ought to have something to say about how a general may and may not be attacked.

If I remember correctly, the assailant must be dressed in some sort of military uniform to be considered a prisoner of war if captured. Lacking the uniform, it would be espionage and no Geneva Convention rights.

Obviously, neither side in the conflict is adhering to these rules.

I should give this a read:
