RLE and Draken...
The F-35 advocates may be correct in saying that there are threats against which the jet's level of LO may be effective, and where a Typhoon or Rafale can't go without a lot of support and/or with high risk. But there are a few points beyond that.
Such threats (double digit SAMs, for instance) will never be ubiquitous or cover the entire airspace.
They may evolve to the level where even an F-35 will not get it, drop a JDAM and get out again.
As we have seen, going downtown against fixed heavily defended targets is not the only fighter mission, and there are others where LO is not relevant or barely so.
The Euros all recognized the value of LO for heavily defended targets, which is why we have Storm Shadow/SCALP and Taurus. Back in the day of a $35 million, lower-then-F-16-operating-cost JSF you could argue that this was a more expensive solution. In 2018, who knows - and in the 2020s you can add the VLO UCAV option.
