Israel has negotiated and signed peace treaties with Egypt and Jordan. I don't understand in what sense you would say that these are 'cease fires', and how that relates to the article's point.
If we say that a 'cease fire' that later turned into a 'peace treaty' doesn't count as a successful peace treaty then of course it looks like 'cease fires' only result in failures.
If the resumption of hostilities qualifies as a failure, then I would have to say a permanent armistice and a peace treaty would have to be qualified as a success.
