Who knows? It depends on too many factors. The most obvious point is Estonia, specifically Narva. If you have a city full of discriminated non-citizens, bordering with Russian Federation, and your largest party is pro-Russian (but not alllowed in the ruling coalition) - it's clearly very inflammatory situation. Estonian Nazies attack ethic Russians, protesting against discrimination, local Russians fight back, with support of local pro-Russian Estonians took power in Tallinn and rename it back in Kolivan, sign alliance with Russian Federation. NATO countries doesn't recognise new government and send their military forces to supress the rebels. Russian Federation send forces to defend the ally and fight NATO invasion forces. But exactly because the situation is that predictable - its unlikely to happen.
More likely situation with escalation over Ukraine and France if Russia see French nuclear program as a vital threat. May be it will be another Russian-Turkish war over domination in former Georgia or former Yugoslavia.
All I do is gather and evaluate information. And it's not that I have a lot of it. You guys keep asking me to tell fortunes, but I don't know how. What I do know is that what is happening now is going to ignite the biggest firestorm since Hiroshima, and sure as hell have to try to do something before it burns up a whole region.
