Chinese government still treats North Korea as an ally, hope to keep US at the bay and hold a so called â€œbuffer â€œarea. Maybe Chinese leaders care more about ideology than their countryâ€™s interest. But if such short sighted policy doesnâ€™t change, China will shoot her own foot in the future. North Koreaâ€™s dictator is enjoying his cat and mouse game right now. He never wants to be disciplined. He will do anything to keep himself and his family in power, even millions of people loses their life. However, North Koreaâ€™s collapse is imminent. Korea will be eventually united. Not by North though. Dear leader and his family will be remembering as one of the most brutal dictators in human history. By then what Korean people would think about China? How would they or the world teach their future generations about this page of history, and Chinaâ€™s role in it? Maybe China doesnâ€™t care, because China is powerful. But power itself doesnâ€™t get respect. US is powerful. She supported Chinaâ€™s civil war in 1940â€™s, how many Chinese appreciated it? The Chinese government even took advantage of it and â€œeducatedâ€ Chinese to hate â€œUS imperialist â€œfor decades. As a world power, China should treat her neighbors in a responsible way instead of making same mistake US made decades ago. In terms of â€œbuffer zoneâ€, thatâ€™s nonsense. In todayâ€™s world, North Koreaâ€™s few hundred kilometers inland is meaningless. F-22 can fly from Japan to Chinese border in 45 minutes. A Los Angeles class Nuclear submarine can reach Yellow sea in 36 hours from Guam. China didnâ€™t need any â€œbuffer zoneâ€ in 1960â€™s when Soviet Union had a million strong army staged by Chinese border, why they need it today? Korea is Chinaâ€™s neighbor, so do many countries surrounding China. They are watching Chinaâ€™s action toward her neighbors closely. Such policy is increasingly showing signs of trouble. China is constantly embarrassed by North Koreaâ€™s actions. Chinaâ€™s security is getting worse instead of getting better. Her neighbors are nervous. Itâ€™s time for Chinese government to show some responsibility.
