Secretary of State Henry A. Kissinger "dismissed" a 1973 intelligence report quoting Soviet leader Leonid I. Brezhnev as saying the Soviet Union would capture military and economic advantages by playing with detente, the Boston Globe said yesterday.

The report, relayed by British intelligence, was "denigrated and dismissed" by kissinger, the newspaper quoted sources as saying. Kissinger was the architect of detente.

Brezhnev reportedly made the statements to Eastern European Community Party leaders in Prague to allay fears the Soviet Union was jeopardizing Eastern European interests.

"Trust us comrades," Brezhnev was quoted as saying. "For by 1985, as a consequence of what we are now achieving with detente, we will have achieved most of our objectives in Western Europe. We will have consolidated our position. We will have improved our economy. And a decisive shift in the correlation of force will be such that, come 1985, we will be able to exert our will wherever we need to."

While Kissinger reportedly downplayed the importance of Brezhnev's statements, the newspaper report said British officials viewed the statements as comparable to the text of Nikita S. Khrushchev's 1956 speech denouncing Joseph Stalin.

"We are achieving with detente what our predecessors have been unable to achieve using the mailed first . . . We have been able to accomplish more in a short time with detente than was done for years pursuing a confrontation policy with NATO," Brezhnev reportedly said.
