How did the US Congress respond to the signing of the SALT II (Strategic Arms Limitation Talks) treaty?

The SALT II treaty was signed by President Jimmy Carter and Soviet leader Leonid Brezhnev in 1979, but the U.S. Senate never ratified it. After the Soviet invasion of Afghanistan, Carter asked the Senate to postpone consideration, and the treaty did not take effect. So the best choice is “Congress refused to ratify the treaty.”
