Newsweek has learned that Secretary of State James Baker this week will formally protest a Soviet plan to place an SS-4 intermediate-range missile in Cuba. The Soviets say it won't be operational and it's going into a museum. But U.S. officials see the plan as a worrisome reminder of the 1962 Cuban missile crisis. "This just reopens old wounds," says an administration source.

Under the INF treaty, the Soviets must destroy, their intermediate-range missiles. Washington agreed to permit Moscow to keep an inoperative SS-20 in a museum at a missile-training base in the Soviet Union. But the new plan for housing an SS-4, even one that's been disabled, in Cuba is too close to home.
