It later became popular again during the Gulf War in 1991 and after the September 11, 2001, attacks (becoming his highest charting pop hit, reaching number 16 on the Billboard Hot 100), and again during the 2016, 2020 United States presidential elections and 2024 as President Donald Trump's rally introduction track.
