You admire the fluid symmetries of troops on the move, the harmonies of sound and shape and proportion, the great sheets of metal-fire streaming down from a gunship, the illumination rounds, the white phosphorus, the purply orange glow of napalm, the rocket’s red glare. It’s not pretty, exactly. It’s astonishing. It fills the eye. It commands you. You hate it, yes, but your eyes do not.
