'Unámonos contra la agresión' [Let Us Unite Against Aggression]
Three fists grip a pole from which a banner of the American republics' flags hangs, while a black snake coiled around the banner is impaled on the pole's spear tip. Bandwagon: the massed flags and the call 'Let us unite' present joining the hemispheric bloc as the shared, expected course. Name-calling: the aggressor is shown as a snake, a label by image with no named enemy.
