(a phrase taken out of The
United States foreign policy):
a phrase meaning: as long as I have a common enemy with a given
person and I will take the risk that this friend of mine might betray me
later.
Jason: James my man, why the heck are you friends with Robert? He convince you and Alison to break up and the took Alison's virginity anyways.
James: Listen, my enemy's enemy is my friend. What I mean is, Alison and I were already having relationship issue before Robert became a regular at the bar where she then worked. Not only that but Robert and I had a common enemy, whose name is
Carl, and we became friends before the whole affair with Alison simply Robert hates
Carl because
Carl stole his car. And I hate
Carl because he borrowed
money from me to pay rent on a stupid storage locker and never bothered paying me back.
Jason: so now the you and Robert want to gang up on
Carl? and you don'
t care about Robert betraying you? wtf?
James: Don't know yet, but Robert and I became friends because we did have a common enemy,
Carl. and I don't care about Robert's betrayal, because I took that risk when I became friends with him.
