Shift in Russian intelligence operations on US soil

Intelligence

An unsealed indictment and reports from exiled dissidents indicate that the Kremlin may have abandoned the taboo against targeting individuals on US territory. This represents a shift in the "Moscow rules" that previously governed spy behavior in rival nations. This follows a familiar trajectory. When institutional constraints are viewed as liabilities rather than safeguards, they are discarded. The result is usually a period of unpredictable escalation, as the previous boundaries no longer provide a reliable framework for managing risk.
