The latest news that DS and DSS (and G17) agreed to form a government seems like the 'playing chicken' phase of government formation is over. So electing Nikolic might turn out to have been a similar bluff (and hopefully shortlived) like Velja Ilic's talk about a DSS minority government with radical support a few weeks ago. The key question now to find out is who blinked first: DS or DSS. For a while DSS had the stronger card as they could (theoretically) form an alternative government to a coalition with DS. However, the threat of new elections, just a few days away, seems to be benefiting DS rather than DSS, as they could be portraying themselves as the only/last bastion against radicals in government.
Now the question is whether the other chicken game--between the USA and Russia--in the UN security council will be similarly resolved.
