NO

Problem:
 if(true()) -> X
 if(false()) -> Y
 p(0()) -> 0()
 p(s(X)) -> X
 leq(0(),Y) -> true()
 leq(s(X),0()) -> false()
 leq(s(X),s(Y)) -> leq(X,Y)
 diff(X,Y) -> if(leq(X,Y))

Proof:
 Fresh Variable Processor: loop length: 1
                           terms:
                            if(true())
                           context: []
                           substitution:
                            X -> if(true())
