Today, Yellow sea, once a peaceful area, becomes a quasi battle field. Menacing bastilles whistle all around. Formations of warships disturbed the once sacredly tranquil area in the earth. Americans and Koreans are carrying out a precedented military exercise now. The first time in history, Washington, a well-known American aero plane carrier, intrudes in this piece of sea, facing directly to Beijing. Astonishing news come that there are about 400,000 soldiers taking part in this united military exercise. Americans and Koreans are grinding their knives to prepare to challenge our strategic interests. What shall we do? Some people say that we should serve them with the same sauce. But my answer to this complicated situation is waiting and seeing. We need not to fight with a seemingly strong adversary now. What we need to do is reading Sun Tzu's military strategies loudly. In another word, we should still need to stick to conceal one’s ability and bide one’s time. Why I say so isn’t for we are coward and don’t dare to fight tit for tat with impolite offenders. Instead, we are facing a timid adversary. First, we have known our old pat, America, thoroughly. It often shows his muscle when its economy is relevantly strong. But now, when we unveil the military fig leaf of American, we can see a nervous president and a plummeting economy of America. Yes, its economy is still strong enough to challenge any country, but it seems like a hollow giant if it can’t find a suitable remedy for its plagued economy. Recently, important areas of America, including real estate, export and consumption, show signs of sliding down. Some experts rest assure that a double-bottom crisis is fermenting. And Mr. Obama is facing more difficult challenges in the upcoming mid-term collection. Against such backgrounds, we can see the limitations of American and his allies. The military exercise in Yellow sea is just a trick to divert people’s attentions on economy difficulties and satiate American’s still-fresh dream of hegemony. I just remember Chairman Mao once said:”we should look down on our enemy on strategies while pay attention to them on tactics” We still need do what we can do to prepare for worst situations. But we should not let go the first shot. Peace is a good thing we still need it as long as it can be gain through diplomacy and high-level strategies.  Second, America people don’t want to have another fight. We still have fresh memory that so many anti-war demonstrations out broken in America related to the unpopular wars in Iraqi and Afghanistan. What American people concerns are income and stable economy situation? Not war! We must rest assure it. Any American politician, no matter how fickle it is, dares not to fan a new war again. So, we can make sure that American troop is just only showing its muscle to intimidate others. Of course, the feeling of letting others stamp our interests is not so tasty. But we can judge the palates of American politicians feel not good to. A guy with hate in its heart can’t taste good things.
