Washington, DC – FE Warren Air Force Base and two other nuclear missile bases were spared in this year's round of base closings. But a Pentagon review of military strategy expected early next year could signal major changes. Military officials and experts say the most likely scenario is a change in the mission for the bases. One suggestion being discussed is arming the missiles with conventional warheads that could hit anywhere in the world with great precision. One Washington think-tank says converted missiles could be to take out terrorist leaders and other far-flung target. But other military experts say that is unrealistic. They say countries would assume an ICBM coming from one of the three bases was nuclear, and it might trigger a nuclear response.
