In this Essay, Senator Jon Kyl argues that the Senate's October 1999 reject
ion of the Comprehensive Test Ban Treaty (CTBT) was justified because it wa
s flawed ineffective, and if ratified would have threatened the security of
the United States. Senator Kyl believes ratification of the CTBT would hav
e (1) jeopardized the safety and security of the United States nuclear arse
nal, (2) failed to curb nuclear proliferation, and (3) been neither verifia
ble nor enforceable. He recommends that, rather than signing on to the CTBT
, the United States ensure its security, and that of its allies, through a
strong military deterrent and better enforcement of existing agreements.
