President Richard Nixon pursued a foreign policy of détente, seeking to reduce tensions with China and the Soviet Union through diplomacy. His administration established relations with China and pursued arms limitations with the Soviet Union. However, Nixon's presidency was embroiled in the Watergate scandal after operatives working for his re-election campaign broke into the Democratic National Committee headquarters. This led to Nixon's resignation in 1974 to preempt impeachment. The scandal undermined public trust in government and established limits on executive power.
