, co-director and senior scientist

Articles citing a classified 2011 report by the Institute for Defense Analysis (IDA) have mistakenly suggested the report finds that a constellation of only 24 satellites can be used for space-based boost-phase missile defense.

US observers wondered whether China felt threatened by the summit and intentionally undermined it.

What Does North Korea Want—and What is the US Prepared to Give?

, co-director and senior scientist
