No doubt it's an excellent strategy to identity where any future/potential opposition may come from.

As Sun Tzu says in The Art of War:

"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.

What if you know the enemy, but not yourself?

You will spend $750B per year on a military that hasn't won a war in generations.

Or just never won a high intensity war alone.

I'll answer that with an examiner's question:

Please provide a T-F truth table to show that the proposition is false.

Clue: you already have the answer and Sun Tzu has provided three-quarters of it
