Holding senior planners accountable in grey zone operations requires bypassing the immediate handler. Zhykovych served as a firewall, but the architects often hide behind plausible deniability.
Universal jurisdiction allows national courts to prosecute grave crimes regardless of where they occurred. If the bombing is classified as a crime against humanity, a third-party state could issue arrest warrants. This effectively restricts the architects' travel, turning them into prisoners within their own borders.
Targeted sanctions, such as those under Magnitsky-style laws, offer a faster alternative to a trial. These measures freeze foreign assets and revoke visas for individuals tied to state-sponsored violence. It avoids the difficulty of a courtroom confession by hitting the target's wealth and social status.
Intelligence leaks also strip away the veil. When a name appears in a declassified memo or a defector's testimony, the political cost of protecting that person rises. These mechanisms create a slow-motion squeeze. They don't always end in a jail cell, but they erode the safety that state deniability usually provides.
