Do robbers go after cops ? Or do they go after those who mind their own business ?
You guys often boast how much China is a 'civilizational state', pretty much in a class by her own. Rightly deserved.
But THAT is precisely the reason why China must be more proactive against terrorism. We may have ideological and political differences and those differences may even lead to war, but that does not take away from the fact and truth that without such distinguished civilizations -- like China -- throughout, mankind will have no hope to the future and would have perish a long time ago.
Look at world history. The Irish reputedly 'saved' Western civilization. The Romans conquered territories and marked them with their cultural imprints. The British and the Europeans made themselves known with their 'tall ships' and travels. The list of contributors to mankind's progress is long and each time a nation rise to historical prominence, mankind take one more step on the evolutionary ladder. China did not merely rose to historical prominence but somehow throughout the thousands of yrs of history, have sustained herself there, being a beacon of hope for some, an item of curiosity for some, or a point of destination, whether physically or ideologically, for others. China had her moments of weakness but also her times of strength and power.
China may not have a legal duty to participate in the fight against those who would regress the world, but if China have even a shred of self respect for her contribution to world's history, there is a moral burden upon China to aid in the resistance to any attempt to force mankind to turn our backs on our future. The more nations becomes interconnected to each other, like woven cloth, the greater the burden is upon those who for any and many reasons are dominant in global affairs to take the lead in fighting terrorism.
You are seriously wrong in believing that if you 'mind your own business' that China will be left alone.
