Should the Saint-Nazaire shipyards be nationalized?

This was the question Trendeo's managing director David Cousquer was asked to answer on LCI on May 5.

This question arises in the wake of STX's decision to sell its European shipyards. The shipyards have a fairly satisfactory order book, and buyers should be found. It remains to be seen whether these buyers will be French, as part of a complex solution, or whether STX will sell more quickly, possibly at a lower price, to foreign buyers.

Between the two solutions, could a temporary portage by the State offer a more satisfactory takeover solution?
