Which led to an increase in Cold War tensions between the US and the USSR in 1983?

In 1983, U.S.-Soviet talks on limiting nuclear weapons in Europe broke down, increasing distrust and tensions. The INF Treaty was not signed until 1987, after negotiations resumed, so the signing itself did not cause the 1983 rise in tensions. The correct choice is a breakdown in arms-control negotiations.
