He was previously a U.S. Foreign Service Officer for 25 years, last serving as Director of the Strategic, Proliferation and Military Affairs Office in the Department of State’s Bureau of Intelligence and Research. His foreign posts include Deputy Political Counselor of the U.S. Embassy in Brasilia, Brazil; Political-Military Affairs Officer in Moscow, USSR; and Political-Military Affairs Officer in Bonn, Germany.

His July 2003 appearance at an ACA press briefing on faulty intelligence assessments on Iraq’s WMD capabilities led to a CBS News 60 Minutes II segment “The Man Who Knew,” which won an Emmy Award for reporter Scott Pelley.
Greg Thielmann's primary research areas include:
It may be necessary to exploit Russia’s interest in preventing the enlargement of strategic missile defenses.
Asian states Pakistan, India, China, and North Korea comprise four of the world's nine nuclear-armed states. The interconnections of these countries must be considered to fully understand how nuclear nonproliferation can be influenced.
In relying on threat assessments, it is wise to ask about the track records, evidence, and probabilities.
