The Strategic Defense Initiative was a U.S. missile defense program that played a very prominent role in the U.S.–Soviet relationships in the 1980s and is often credited with helping end the Cold War, as it presented the Soviet Union with a technological challenge that it could not meet. This article introduces several official Soviet documents to examine Soviet response to SDI. The evidence suggests that although the Soviet Union expressed serious concerns about U.S. missile defense program, SDI was not a decisive factor in advancing arms control negotiations. Instead, the program seriously complicated U.S.–Soviet arms control process. SDI also failed to dissuade the Soviet Union from investing in development of ballistic missiles. The Soviet Union quickly identified ways to avoid a technological arms race with the United States and focused on development of advanced missiles and anti-satellite systems to counter missile defenses. Some of these programs have been preserved to the current day.  相似文献

ABSTRACT

Nuclear disarmament is often seen as eventually requiring access to nuclear warheads or to the warhead-dismantlement process to verify that a state has not hidden weapons or weapon-materials despite promising to disarm. This article suggests this view is misplaced, and that what is needed is a verification mechanism able to provide reliable assurances of the absence of fissile materials available for use in weapons after a state has disarmed. Such a mechanism will need an initial declaration of the amount of fissile materials held by a state for all purposes, military and civilian. In a state with a nuclear arsenal awaiting elimination, this declaration would have to include materials that may not be available for verification because they are in nuclear weapons or are in other classified or proliferation-sensitive forms. This article describes a verification arrangement that does not require access to materials in weapons and in sensitive forms while still allowing checks on the overall accuracy of the declaration. Verification of the completeness and correctness of the declaration is deferred to the time when the weapons-relevant material enters the disposition process, at which point it no longer has any sensitive attributes. By removing the focus on monitoring warheads and dismantlement, this new approach could provide a more manageable path to nuclear disarmament.  相似文献

High-level declarations in Moscow and Beijing on the steady progress in upgrading their strategic partnership depart increasingly far from the reality of shrinking economic ties and diverging political perspectives. In late 2014, the dynamic development of this partnership appeared to have the potential of becoming a major shift in the fluid security balance in the Asia-Pacific region; in late 2015, however, the concerned neighbours have more reasons to worry about the deformations in the development of Russia–China relations. President Vladimir Putin and President Xi Jinping are eager to demonstrate perfect personal rapport but their mutual trust is open to doubt and their views on priorities of domestic and international order are in fact strikingly dissimilar. The deep contraction of trade and the lack of interest from Chinese investors propels the Russian leadership towards increasing the emphasis on the security dimension of the partnership, and this makes Russia one of the key sources of instability in the Asia-Pacific region and a challenge to the East Asian peace. It is also entirely possible that the Russian challenge to the stability of the world system would result in strengthening of the key institutions of its governance, thus leaving the revisionist Russia in isolation.  相似文献
