That's the black helicopter tin foil obfuscated answer. I'm talking about open dialog like most people have.
So let's talk openly with unobfuscated dialog. Theoretically, if a state goes to war because they were provoked--in other words, they didn't initiate the force, the other party did, and this state was just protecting itself from agression of another, does that state have the right to kill to protect its citizens? And if it has the right to kill to protect itself, does it also have the right to extract information from the enemy using unpleasant means?
States go to war because war is the health of the State. Citizens suffer the whims, deceptions and wars of the State.
You're not very good at this.
