NO

Problem:
 strict:
  f(s(x),y) -> f(-(s(x),y),y)
 weak:
  +(0(),y) -> y
  +(s(x),y) -> s(+(x,y))
  -(x,0()) -> x
  -(0(),y) -> 0()
  -(s(x),s(y)) -> -(x,y)
  f(x,y) -> f(x,+(x,y))

Proof:
 Unfolding Processor:
  loop length: 2
  terms:
   f(s(x),0())
   f(-(s(x),0()),0())
  context: []
  substitution:
   x -> x
