Furthermore, the current Cold War model of the Japan-US alliance is outdated and troop presence is uniquely contentious
Congressional Research Service ’09 (Emma Chanlett-Avery (specialist in asian affairs) and Weston S. Konishi (analyst in asian affairs) Congressional Research Service: “The Changing U.S.-Japan Alliance: Implications for U.S. Interests” July 23, 2009)
Some analysts argue that the Cold War formula for the U.S.-Japan alliance is outdated and that the forward presence of 53,000 U.S. troops is an unnecessary burden to the U.S. military.They assert that Japan has the resources to develop into a more autonomous defense force and could cooperate with the U.S. military in areas of mutual concern on a more limited, “normal” country- to-country basis. Further, advocates argue that the eventual withdrawal of U.S. forces from Japanese soil could cement a more durable strategic partnership than the current configuration.31 Opponents of this strategy argue that the large-scale U.S. military presence is necessary in a region with simmering tension and the rise of China, a power that may challenge U.S. hegemony in Asia. Some military experts argue that reducing the number of Marines stationed in Japan, while maintaining air and sea assets, could reduce some of the burden on local communities and still maintain a strong U.S. deterrence in the region.
Japan Withdrawal – 1AC [3/10]
Strong US-Japan alliance is key to solving Chinese invasion of Taiwan through economic interdependence
Nye, 2008 [Joseph Nye, 5-12, Korea Times, “Future of US-Japanese Alliance,” Lexis]
Japan and the U.S., unlike China, are both democracies, and they share many values. In addition, both Japan and the U.S. face a common challenge from China's rise and have a strong interest in ensuring that it does not become a threat. The U.S. regards a triangular Japan-China-U.S. relationship as the basis of stability in East Asia, and wants good relations between all three of its legs. But the triangle is not equilateral, because the U.S. is allied with Japan, and China need not become a threat to either country if they maintain that alliance. On the other hand, China's power should not be exaggerated. A recent poll indicates that one-third of Americans believe that China will "soon dominate the world," while 54 percent see its emergence as a "threat to world peace." To be sure, measured by official exchange rates, China is the world's fourth largest economy, and it is growing at 10 percent annually. But China's income per capita is only 4 percent that of the U.S. If both countries' economies continue to grow at their current rates, China's could be larger than America's in 30 years, but U.S. per capita income will still be four times greater. Furthermore, China's lags far behind in military power, and lacks America's "soft power" resources, such as Hollywood and world-class universities. China's internal evolution also remains uncertain. It has lifted 400 million people out of poverty since 1990, but another 400 million live on less that $2 per day. Along with enormous inequality, China has a migrant labor force of 140 million, severe pollution, and rampant corruption. Nor has its political evolution matched its economic progress. While more Chinese are free today than ever before in Chinese history, China is far from free. The danger is that party leaders, trying to counter the erosion of communism, will turn to nationalism to provide ideological glue, which could lead to an unstable foreign policy ¡ª including, for example, conflict over Taiwan. faced with such uncertainty, a wise policy combines realism with liberalism. By reinforcing their alliance, the U.S. and Japan can hedge against uncertainty while at the same time offering China integration into global institutions as a "responsible stakeholder." The greatest danger is that an escalating fear of enmity in the three countries becomes a self-fulfilling prophecy. In that sense, the U.S.-Japan alliance rests on deeply rooted joint interests.
And, war over Taiwan causes extinction
Strait Times, 2000 [“Regional Fallout: No one gains in war over Taiwan,” Jun 25, LN]
THE high-intensity scenario postulates a cross-strait war escalating into a full-scale war between the US and China. If Washington were to conclude that splitting China would better serve its national interests, then a full-scale war becomes unavoidable. Conflict on such a scale would embroil other countries far and near and -- horror of horrors -- raise the possibility of a nuclear war. Beijing has already told the US and Japan privately that it considers any country providing bases and logistics support to any US forces attacking China as belligerent parties open to its retaliation. In the region, this means South Korea, Japan, the Philippines and, to a lesser extent, Singapore. If China were to retaliate, east Asia will be set on fire. And the conflagration may not end there as opportunistic powers elsewhere may try to overturn the existing world order. With the US distracted, Russia may seek to redefine Europe's political landscape. The balance of power in the Middle East may be similarly upset by the likes of Iraq. In south Asia, hostilities between India and Pakistan, each armed with its own nuclear arsenal, could enter a new and dangerous phase. Will a full-scale Sino-US war lead to a nuclear war? According to General Matthew Ridgeway, commander of the US Eighth Army which fought against the Chinese in the Korean War, the US had at the time thought of using nuclear weapons against China to save the US from military defeat. In his book The Korean War, a personal account of the military and political aspects of the conflict and its implications on future US foreign policy, Gen Ridgeway said that US was confronted with two choices in Korea -- truce or a broadened war, which could have led to the use of nuclear weapons. If the US had to resort to nuclear weaponry to defeat China long before the latter acquired a similar capability, there is little hope of winning a war against China 50 years later, short of using nuclear weapons. The US estimates that China possesses about 20 nuclear warheads that can destroy major American cities. Beijing also seems prepared to go for the nuclear option. A Chinese military officer disclosed recently that Beijing was considering a review of its "non first use" principle regarding nuclear weapons. Major-General Pan Zhangqiang, president of the military-funded Institute for Strategic Studies, told a gathering at the Woodrow Wilson International Centre for Scholars in Washington that although the government still abided by that principle, there were strong pressures from the military to drop it. He said military leaders considered the use of nuclear weapons mandatory if the country risked dismemberment as a result of foreign intervention. Gen Ridgeway said that should that come to pass, we would see the destruction of civilisation. There would be no victors in such a war. While the prospect of a nuclear Armaggedonover Taiwan might seem inconceivable, it cannot be ruled out entirely, for China puts sovereignty above everything else.
