Eight-three percent said prevention of the spread of nuclear weapons should be a top priority, while 82 percent said securing adequate energy supplies for the United States was their top priority.
The remaining six issues Gallup included in its survey were, in order, promoting favorable trade policies, defending allies' securities, working with groups such as the United Nations to bring about world cooperation, promoting and defending human rights in other countries, promoting economic development in other countries and helping other countries build democracies.
