The International Institute for Strategic Studies (IISS) is a defence and security think tank that has a deep understanding of regional geopolitics and geo-economics in a global context. Its international researchers provide best-in-class, independent and impartial analysis and offer insights on strategic challenges and priorities to governments and the private sector.
