The Star Spangled Banner is the only national anthem in the world that contains references to blood, terror and bombs.
'And the rockets' red glare, the
bombs bursting in air' [Verse 1, Line 5]
'Their
blood has washed out their foul footsteps' pollution' [Verse 3, Line 4]
'From the
terror of flight, or the gloom of the grave' [Verse 3, Line 6]
'Then
conquer we must, when our cause it is just' [Verse 4, Line 5]
Musa Cerantonio says this is appropriate considering
the USA is the largest employer of bombs upon other nations in the world, and the only nation to have ever used an atomic bomb to kill its enemies.
