The Obama administration's phased-adaptive architecture: technological,operational and political issues

In 2009, the Obama administration announced a new missile defense strategy, termed a phased-adaptive architecture (PAA) focused primarily on countering the growing threat from theater ballistic missiles. The success of this strategy is predicated on the rapid development and fielding of successive increments of defensive capability in a manner adapted to the specific requirements for missile defenses in different regions of the world. The administration is committed to building a European regional missile defense system, the European PAA or EPAA between now and 2020. The first elements of the EPAA were deployed in late 2011. However, much progress is still required in order to reach the goals set for the PAA. This article addresses the technological, operational and political issues confronting the Obama administration in its efforts to make the PAA a reality.

Involving the elephant: technical isolation and the role of India in a possible solution to the Iranian nuclear crisis

Apart from North Korea, no state's nuclear program in the twenty-first century has raised more concern to international security than Iran's. While Iran insists that its nuclear program is strictly for civilian purpose in line with Article IV of non-proliferation treaty, the USA and its allies insist that Iran has military intentions and called for sanctions. The failure of sanctions to deter Iran from its nuclear agenda had made many scholars and policy-makers call for a preemptive attack on Iranian nuclear facilities. Situated within this debate, this paper positions itself as an antagonist to the preemptive airstrike option and argues that involving India in a possible nuclear “iron curtain” against Iran – a move known as technical isolation – remains the best option to the current nuclear crises.
