George Gilder has been one of our most interesting and important public intellectuals since the 1970s, so his pro-China commentary today in the Wall Street Journal deserves a more serious response than, say, the mindless boosterism of the average Tom Friedman column. In fact, I agree with him that it is hardly worth wasting American diplomatic capital with China on the issues of global warming and the value of the Chinese currency.

I am surprised, however, to see Gilder — who has been an Internet visionary — so blithely suggest that the U.S. government has no stake in Google’s battle with China over Internet censorship and hacking. “Protecting information on the Internet is a responsibility of U.S. corporations and their security tools, not the State Department,” he writes. That is like saying that protecting downtown New York is the responsibility of the corporations headquartered there, not the FBI and NYPD. Cyber infrastructure is fast becoming even more important than physical infrastructure to the functioning of the U.S. economy. Accordingly, it is, indeed, an issue for the State Department — and not only the State Department but also the Defense Department, the Justice Department, and other government agencies.

I am even more surprised to see Gilder — known as a relentless defender of Israel — seemingly write off another embattled democracy: Taiwan. His stance here is a bit contradictory. On the one hand, he writes: “Yes, the Chinese are needlessly aggressive in missile deployments against Taiwan, but there is absolutely no prospect of a successful U.S. defense of that country.” On the other hand: “China, like the U.S., is so heavily dependent on Taiwanese manufacturing skills and so intertwined with Taiwan’s industry that China’s military threat to the island is mostly theater.” Those propositions would seem to be at odds: is China a threat to Taiwan or not? In any case, neither proposition is terribly convincing.

Conquering Taiwan would require China to oversee the biggest amphibious operation since Inchon. Stopping such a cross-Strait attack would not be terribly difficult as long as Taiwan has reasonably strong air and naval forces — and can call on assistance from the U.S. Navy and Air Force. Taiwan doesn’t need the capability to march on Beijing, merely the capability to prevent the People’s Liberation Army from marching on Taipei. It would be harder to prevent China from doing tremendous damage to Taiwan via missile strikes but by no means impossible, given the advancement of ballistic-missile defenses and given our own ability to pinpoint Chinese launch sites. Moreover, giving Taiwan the means to defend itself is the surest guarantee that it won’t have to. Only if Taiwan looks vulnerable is China likely to launch a war.

The notion that such a conflict is out of the question because of the economic links between Taiwan and the mainland is about as convincing as the notion — widely held before World War I — that the major states of Europe were so economically dependent on one another and so enlightened that they would never risk a conflict. If the statesmen who ran Austria and Germany and Russia and France and Britain were, in fact, primarily interested in economic wellbeing, they would never have gone to war. But other considerations — national honor and prestige and security — trumped economics back then and could easily do so again, especially because the legitimacy of the Chinese regime is increasingly based on catering to an extreme nationalist viewpoint.

That doesn’t mean we should engage in needless and self-destructive confrontations with China over global warming and currency, but that also doesn’t mean we should mindlessly kowtow to China’s every whim. As I argued in this Weekly Standard article in 2005, we should pursue a balanced approach to China, tough on security and human-rights issues but accommodating on trade and currency policy. In other words, we should make clear to China that we are prepared to accept it as a responsible member of the international community but that we will not overlook its transgressions, like its complicity in upholding rogue regimes (Sudan, Iran, North Korea) and threatening democratic ones (South Korea, Taiwan).
