Last week, George Washington University's National Security Archive (NSA) posted this briefing book on the ABM treaty in anticipation of this week's talks between Putin and Bush, which covered, among other topics, missile defense issues. The 42 newly declassified documents posted here "reveal the previously secret inside story of the ABM negotiations, explaining why the U.S. and the USSR agreed that the Treaty was in their best interest, and how it specifically restricts what the Bush administration can do on missile defense."
