T.V. Paul: Power Versus Prudence: Why Nations Forego Nuclear Weapons
From T.V. Paul's excellent book: Power Versus Prudence: Why Nations Forego Nuclear Weapons, here is an executive summary of his chapters on Japan, Brazil and Argetina.
JAPAN
Thesis: Non-nuclear policies were adopted in order to maximize economic and security goals within the constraints imposed by asymmetrical security interdependence with allies and adversaries.
Main Points:
• Three Phases of Japanese nuclear policy development:
o 1945-1970: Strong domestic opinion against nuclear weapons. A defensive posture allowed Japan to concentrate on their economy. The U.S. security guarantee helped make possible the Yoshida Doctrine of 3 non-nuclear principles: no producing, no possessing, and no nukes on Japanese territory (no written agreement = deniability)
o 1970-1990: Japan ratified the NPT in June 1976 after receiving IAEA agreement to less intrusive safeguards and treatment equal to Euratom. Increased Soviet activity led to re-examination of nuclear decision. First and second strike capabilities explored; ineffective effective deterrent due to high degree of urbanization.
o 1991 and beyond: Japan's Low-posture defense to project an image of benign trading state. Japan's Prosperity and economic security became enmeshed in global web of financial, production, and trading interdependencies. Nuclear weapons would be viewed with intense suspicion by regional states, potentially worsening security environment.
• Japan possesses a latent nuclear weapons capability and could go nuclear under the following conditions:
o A Worsening of security environment following a loosening of U.S. security commitment – unlikely in short and medium term.
o Power and prestige – unlikely, development of defensive technologies is more likely
o Rise of China as military power and threatening posture towards Japan – deterrent capabilities, nuclear weapons, or strengthening of relationship with U.S.
ARGENTINA AND BRAZIL
Thesis: Perceived utility of nuclear weapons changed when Argentina and Brazil resolved their territorial disputes; changes in domestic power structures accelerated and reinforced the process.
Main Points:
• Both states opposed the NPT because its discriminatory nature and its alleged negative impact on their independent nuclear energy programs.
• At the time they signed the NPT, both states (especially Argentina) were advanced enough to fabricate a small nuclear force quickly.
• Background:
Argentina's Motive: to reverse Argentina’s decline; bring back the grandeur of the past. Competition with Brazil drove military component of nuclear program. Wanted military equality with Brazil and preponderance over Chile; prevent politico-military alliances. After 1982 and Falklands/Malvinas War they realized they could not take on Brazil and looked to them as more of a trading partner, not a threat – result policy of cooperation.
Brazil's Motive: Power and prestige and competition with Argentina. Robust military nuclear program in all services. Decided to give up program due to fear of provoking arms race with Argentina, Argentina’s lead in completing the fuel cycle – result policy of cooperation. Mutual recognition that economic integration would not be feasible if military competition continued. Non-nuclear through a bilateral process of agreements, inspections, and confidence building measures with little intervention/help from the U.S. or IAEA.
A simultaneous transition to democracy in the two countries increased the pace of cooperation.
