It's the world's flimsiest alliance, 
bound by a single bottle of cola.
.إنّه أضعف حلف في العالم، مرتبط بزجاجة كولا واحدة
Die zweifelhafteste Allianz der Welt,
begründet auf einer Flasche Cola.
L’alliance la plus frivole au monde,
fondée sur une bouteille de Cola…
Un accordo stretto per una bottiglia di cola...
É a aliança mais tênue desse mundo,
segurada por uma garrafa de Coca.
Самый шаткий на свете союз,
скреплённый бутылочкой колы.
