Brzezinski Sees Perils in Soviet Policy Changes

WASHINGTON — Former national security adviser Zbigniew Brzezinski said Sunday that the release from internal exile of Soviet dissident Andrei D. Sakharov is evidence of a major shift in Soviet policy, a development he said could lead to increased instability in that country.

Appearing from Washington on ABC TV’s “This Week with David Brinkley,” Brzezinski, who was President Jimmy Carter’s national security adviser, said: “I think we’re on the eve of something very significant, perhaps even momentous, happening in the Soviet Union. I don’t think it’s cosmetic at all. I think it’s very serious.

“The fact that (Sakharov) comes back in triumph is a source of enormous encouragement to every would-be dissenter in the Soviet Union,” Brzezinski said.

‘Very Dangerous Game’

“What is happening is that Gorbachev is trying to renovate the system, to rejuvenate it, to make it more modern, without reforming it--and that’s a very dangerous game,” he continued. “. 773860896ultimately you cannot yourself control.”

Brzezinski said that the riots that erupted last week in Alma Ata, capital of the Soviet Asian republic of Kazakhstan, “were perhaps more important than the return of Sakharov” in that they may presage increased unrest among the 45 million Muslims under Moscow’s control.

Brzezinski said he expects the Soviet Union to attempt to take advantage of the Reagan Administration’s preoccupation with the scandal over the sale of arms to Iran.
