Distraction and surprise has always been the greatest tactics of the game. The bull charges at the red flag in the hand of the matador while the dagger doing the damage is in the other hand.
Sometimes a good attacker creates the effect of a massive attack on the east to cause a shift of force to the area which then gives him little or no opposition to attack in the west which really is his strategic target.
It’s the same way a shrewd wicket politician wants to get rid of an opponent; he digs up dirt of the past smilingly unrelated to the present just to create an opening. Some dark forces when faced with warriors too strong for them, in frantic desperation similar to terrorism, they ignore all the decency of modern warfare by targeting defenceless women and children all in the bid to weaken the minds of the fighting warriors.
If you can sense or see an attack approaching an obvious target, do what you must to consolidate your position but look again, if it’s from a deft attacker that’s probably not his target. There is no easy way to defeat a worthy opponent, evaluate your options and make the best choice you can.
