Administration officials said they hoped to complete their months-long review of the planned antimissile system as early as next month, possibly in time for President Obama to present ideas to President Dmitri A. Medvedev of Russia at a meeting in New York during the annual opening at the General Assembly of the United Nations . . .
Among the alternatives are dropping either the Polish or Czech site, or both sites, and instead building launching pads or radar installations in Turkey or the Balkans, while developing land-based versions of the Aegis SM-3, a ship-based anti-missile system, officials said. The changes, they said, would be intended not to mollify Russia, but to adjust to what they see as an accelerating threat from shorter-range Iranian missiles. (photo: Orbital)
