i believe a dragon could safely return one or 2 astronauts safely..

first theres a large lead time, in the event of a soyuz family failure some back up is prudent..

given that today its clear we might need to return astronauts russian or american in a emergency.......


That's part of what the Commercial Manned Space efforts (SpaceX and
Boeing) are supposed to produce. Meanwhile, a Soyuz family failure
that prevents using them to reenter is unlikely. If said 'failure'
coincides with an ISS failure and you HAVE to get off, you'd use the
Soyuz anyway (after all, whatever might be wrong, they've been used a
lot so the risk is still low). If it doesn't, you've got half a year
to work it out.
