International Security & Defense

The human tragedy continuing to unfold in Gaza and Israel reminds us how important it is to get strategic forecasting right. While in no way excusing Hamas’ culpability for 7 October, we also cannot dismiss the fact that the failure to anticipate and prepare for such an attack has had grave consequences for communities on both sides of this conflict, undermined efforts to bring peace and prosperity to the region, and affected global interests through the expansion of the conflict to the Red Sea and potentially beyond. 

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense.

Mariana Budjeryn writes: War never stops at the border, especially on a continent like Europe. The European Union absorbed millions of Ukrainian war refugees and poured billions of euros into Ukraine's defenses and economic survival. The war permanently reshaped Europe: its demographics, political economy, and energy architecture are shifting in ways that will have irreversible long-term consequences. All of this is because in a very real sense Ukraine already is inextricably woven into the fabric of Europe: Ukraine’s pain is Europe’s pain and Ukraine’s gain will inevitably be Europe's gain, too.

Stephen Walt argues that Henry Kissinger's concerns about the destabilizing impact of ideas made him hypersensitive to the smallest perturbations in strategically marginal countries and inclined him to overreact to them in ways that other realists opposed.
