Monuments say I own this land. Castles Courts and Parliaments say I rule this land. Temples and Churches say I control these people.
Removing monuments says I conquered this land. Occupying castles, parliaments, or courts, says I conquered this Government. Building or destroying temples or churches, says I conquered these people.
If one comes upon a territory or its institutions or its people with conquest rather than accommodation, then one comes by way of war.
And the only response to war regardless of means is war.
And there are no laws in war.
