This report assesses domestic political support for internationalist foreign policy by analyzing the motivations of members of Congress on key foreign policy issues. It includes case studies on major foreign policy debates in recent years, including the use of force, foreign aid, trade policy and U.S.-Russia relations. It also develops a new series of archetypes for describing the foreign policy worldviews of members of the 115th Congress to replace the current stale and unsophisticated labels of internationalist, isolationist, hawk and dove. Report findings emphasize areas of bipartisan cooperation on foreign policy issues given member ideologies.

The fair and equitable treatment (‘FET’) standard is a type of protection found in BITs which has become in the last decades one of the most controversial provisions examined by arbitral tribunals. This book first examines the interaction between the ‘minimum standard of treatment’ (MST) and the FET standard and the question why States started referring to the former in their BITs. It also addresses the question whether the FET should be considered as an autonomous standard of protection under BITs. This book also examines the controversial proposition that the FET standard should now be considered as a rule of customary international law. I will show that while the practice of States to include FET clauses in their BITs can be considered as general, widespread and representative, it remains that it is not uniform and consistent enough for the standard to have crystallised into a customary rule. States also lack the necessary opinio juris when including the clause in their BITs.
