Insights
Heimdall connects technical exploitation, supply-chain investigation and practical disruption. These publications examine how evidence can support investigations, anticipate adaptation and sustain pressure on illicit supply chains.
Sanctions Decay, Substitution Elasticity, and the Challenge of Sustaining Pressure
Sanctions should make it harder for Russia to build and use weapons. Damien Spleeters examines how that pressure can fade as restricted components, suppliers and acquisition routes are replaced, and how governments can anticipate those changes, identify dependencies that are harder to replace, and measure whether controls continue to impose costs, delays and performance losses.
Read at CSISTechnical exploitation should not stop at explaining how an adversary acquired yesterday's technology. Identifying critical dependencies and anticipating likely substitutions can help policymakers and industry act earlier, making adaptation slower, costlier, less reliable and more visible.
