I’m not sure if it's better to ask this here or on worldbuilding.se

Which countries except Russia/China/US can launch their own crew into space and return them unharmed (if for some reason this really becomes necessary to do and has to happen quickly) and how long would it take?

Assuming that Mercury/Vostok-1 level is enough, money is not important and the country really wants it done. Also, crew loss could be tolerated if it's a one time thing. Reusing something which is not human-rated could be used as long as it can get the job done.

It should be done without direct help from Russia/China/US (so the country must make its own rocket and ship) but it's ok to use "previous" experience with shared space programs.
