“The verifi cation and compliance regime for a nuclear weapon-free world will need to be more eff ective than any disarmament arrangement hitherto envisaged. One hundred per cent verifi cation of compliance with any international arms agreement is highly improbable. In the case of nuclear disarmament, however, the security stakes will be so high that states will not agree to disarm and to disavow future acquisition of nuclear weapons unless verifi cation reduces to a minimum the risk of non-compliance” VERTIC BRIEF • 1 • MAY 2003 BRIEF Verifi cation of a nuclear weapon-free world Dr Trevor Findlay Dr Trevor Findlay is Introduction Moreover, the same conjunction of good Executive Director of relationships between major states that will e verifi cation and compliance regime for VERTIC.
