So the Swiss government buys BA or AA or UA....than what?
Can't run it out of Zurich, as these are national carriers of other countries.
As for buying any member of the Swissair group, which is chapter 11, it poses one particular problem they don't belong to Swissair anymore. If you have nil - you sell nil!! Although LH is interested in Atraxis and might even want to buy it out, they stand no legal grounds to do so.
