building on that point it is important to note the difference between a tactical strategy and a strategic one.

A war can't be won without winning both. The Vietnamese after world war II lost the tactival war to the French, and the Americans, but one the strategic war on both counts.

Winning on the battlefield is important, but if you can't keep a supply of money, equipment, and morale going then you will lose eventually.

Tactical battles are about exploiting your opponents weaknesses through skill or pure audacity. Strategic battles are fought on a truly grand scale and too complicated to ever fully comprehend. Thousand of variables all interacting with one another.

To be great on that level you must be gifted, inteligent, decisive, and still able to compensate for the butterfly a world away nobody thought to consider.
