Principles of War ( How to wage a war)

Recently I was reading Sun Zi's and Sun Bin's Art of War. I have been reading these two military classics over and over again for many times and I am always impressed by the two military classics everytime.

In Sun Bin's Art of War , it mentions that war should be waged when the reasons are justified and true and not to wage war wantonly. War is a matter of life and death, survival or ruin of the states and country involved. So don't foolishly rush to declare war just because for some stupid and unjustified reasons.

War can be declared and fought if you are under attack of an enemy. ou can repel the enemy or even destroy the enemy by destroying it's core system.War can also be fought against rebels and separationists.

Some times war have to be fought but most war in our history were foolishly waged. The two world wars should never have broken if the Art of war were thoroughly understood and life wouldn't have lost.

As I observe the politics and actions taken between Taiwan and China, I think that if Taiwan were to seperate from Chinese main land and China were to attack, the war can be justified as trying to claim back land and stop seperation.

Imagine a part of the States were to declare seperating from the main land, I guess the mainland would try and recover the seperated part even if it meant war.

Try to imagine a child trying to seperate from his/her mum.

I think that if Taiwan were to buy arms from US and US were to try to sell ams and help Taiwan, it would worsen the relationship between Taiwan and China and US maybe considered a threat too.

Imagine the US as a friend of Taiwan teaching Taiwan and supplying Taiwan with weapons to seperate from it's mum.

Anyway, this is my point of view. each have our own views.
