Russia, China, and the U.S.: Re­cent developments show that power­ful states are increasingly testing the limits of their assertions of power a­gainst other states. To this end, they are using eco­nomic and political pressure, making less and less distinction be­tween permissible and im­permissible means.  

On July 8, 2026, TraCe re­searchers, students, and guests discussed this “New Interventionism” at Justus Liebig University Giessen. 

In the first of two dis­cussion rounds, Lisbeth Zimmermann, Raphaël Cahen, and Hendrik Simon discussed the limits of non­violence and non-interference. The con­versation focused on the various his­torical and contempo­rary forms of interventionism, the e­volution of justi­fication strategies, and the changing scope of action available to the United Nations.

During the se­cond round of dis­cussions, guests Barry de Vries (JLU) and Katja Schöberl (German Red Cross) examined the im­plications of the concept of “neutrality” for states not di­rectly involved in armed con­flicts, including their hu­manitarian respon­sibilities. The ensuing dis­cussion focused on Iran’s re­cent attacks on Gulf states that con­sider themselves neutral but have be­come targets due to the de­ployment of U.S. military forces there.

Summarizing the dis­cussion, organizer Thilo Marauhn stressed the importance of go­vernments consistently up­holding the law. The event con­cluded with an informal exchange.
