Pres. Carter's national security adviser, Zbigniew Brzezinski, says President Reagan should launch a major European ''political initiative,'' Monitor correspondent Godfrey Sperling Jr. reports.
Speaking with reporters over breakfast on March 19, Mr. Brzezinski said the President should:
* offer to cut back on US tactical nuclear warheads in Europe if the Soviets reduce tank forces and tactical nuclear weapons in eastern Europe.
* offer economic aid to Poland in an effort to persuade Warsaw to end martial law.
* begin a ''major political initiative'' to win back support of European allies who are drifting away because of differences over US policy regarding Central America, the Mideast, and East-West relations.
