War is widely thought to be linked to economic good times. World War II is often said to have brought the world out of the Great Depression, and war has since enhanced its reputation as a spur to economic growth. Some even suggest that capitalism needs wars, that without them, recession would always lurk on the horizon.
Today, we know that these propositions are nonsense. The 1990s boom showed that peace is economically far better than war. The Gulf War of 1991 demonstrated that wars can actually be bad for an economy. That conflict contributed mightily to the onset of the recession of 1991 (which, it should be remembered, was probably the key factor in denying former US president George Bush re-election in 1992).
ILLUSTATION: MOUNTAIN PEOPLE
The current situation is far more akin to the Gulf War than to wars that may have contributed to economic growth. Indeed, the economic effects of a second war against Iraq would probably be far more adverse. World War II called for total mobilization, and it was that total mobilization, requiring a country's total resources, that wiped out unemployment. Total war means total employment.
By contrast, the direct costs of a military attack on Iraqi President Saddam Hussein's regime will be minuscule in terms of total US government spending. Most analysts put the total costs of the war at less than 0.1 percent of America's GDP, the highest at 0.2 percent of GDP. Much of that, moreover, includes the usage of munitions that already exist, implying that little or no stimulus will be provided to today's economy.
The US President George W. Bush administration's (admittedly wavering) commitment to fiscal prudence means that much, perhaps most, of the war costs will be offset by expenditure cuts elsewhere. Investments in education, health, research and the environment will almost inevitably be crowded out. Accordingly, war will be unambiguously bad in terms of what really counts -- the standard of living of ordinary people.
America will thus be poorer, both now and the future. Obviously, if this military adventure were in fact necessary to maintain security or to preserve freedom, as its advocates and promoters proclaim -- and if it were to prove as successful as its boosters hope -- then the cost might still be worth it. But that is another matter. I want to debunk the idea that it is possible both to achieve the war's ends and benefit the economy. There is also the uncertainty factor. Of course, resolving uncertainty is no reason to invade Iraq prematurely, for the costs of any war are high, and are not to be measured only, or primarily, in economic terms. Innocent lives will be lost -- possibly far more than were lost on Sept. 11. But the wait for war adds to uncertainties that already weigh on the US, and the global, economy.
First of all their are uncertainties arising from the US' looming fiscal deficit, due to macroeconomic mismanagement and a tax cut that the country cannot afford. Uncertainties arising from the unfinished "war on terrorism." Uncertainties associated with the massive corporate accounting and banking scandals, and the Bush administration's half-hearted efforts at reform, as a result of which no one knows what America's corporations are worth. We must take into account uncertainties connected to the US' massive trade deficit, which has reached all-time records. Will foreigners be willing to continue to lend to the US, with all of its problems, at a rate in excess of a billion dollars a day?
There are also uncertainties associated with Europe's stability pact. Will it survive, and will it be good for Europe if it does?
Finally, there are the uncertainties associated with Japan -- will it at long last fix its banking system, and if it does, how negative will be the short-term impact?
Some suggest that the US may be going to war to maintain steady oil supplies, or to advance its oil interests. Few can doubt the influence that oil interests have on Bush -- witness the administration's energy policy, with its emphasis on expanding oil production rather than conservation. But even from the perspective of oil interests, war against Iraq is a risky venture. Not only is the impact on price, and therefore on oil company prices, highly uncertain, but other oil producers, including Russian and European interests, will not easily be ignored.
Indeed, should the US go to war, no one can predict the effect on oil supplies. A peaceful, democratic Iraqi regime could be established. Desperate for funds for reconstruction, that new regime could sell large amounts of oil, lowering global oil prices. Domestic US oil producers, as well as those in allied countries, such as Mexico and Russia, would be devastated, though users of oil around the world would benefit enormously. Or the turmoil throughout the Muslim world could lead to disruptions of oil supplies, with high prices the result. This will please oil producers in other parts of the world, but will have enormously adverse consequences for the global economy, akin to those resulting from the oil price hikes in 1973. Whichever way one looks at it, the economic effects of war with Iraq will not be good. Markets loathe uncertainty and volatility. War, and anticipation of war, bring both. We should be prepared for them.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
