I think the security development certainly must be a result of other developments than this Arctic issue. Certainly that also will have some aspects. For instance, if there is more trade, more transport and so forth, there may also be complications. That might create some difficulties as far as security is concerned.
Honestly, directly I can't see any major difficulties about this, except that if people start using the raw materials from the sea bottom, for instance, or fisheries, which will be opened because the ice will melt in the north, more seabed will be ready to be explored and used. These kinds of problems would probably be there.
