Ukraine’s military and political authorities continue to seek an adequate deterrent to contain and deter Russian aggression, particularly in light of the breakdown of the 1987 Intermediate-Range Nuclear Forces (INF) Treaty. In response to Washington’s and Moscow’s stated intention, earlier this year, to withdraw from the INF (see Eurasia Daily Monitor, February 4; Kremlin.ru, March 4), the Ukrainian Ministry of Foreign Affairs declared that Kyiv “reserves the right to develop weapons systems deemed necessary to defend itself, including, inter alia, missiles and associated launcher systems” (Mfa.gov.uaMarch 7).
