Earlier quoted context omitted.
Aren't the islands full of Russian people? I imagine a referendum wouldn't yield a result that was unfavourable to Russia.
it depends on the Japan's proposition. If they will propose to guarantee jobs for every new citizen with typical for Japan salary - it will be enough because the exchange rate of Russian ruble is dropped by more than 100% in the last 5 days.
so what we see here is a 20%, max 25% drop of the rubble to the dollar. bringing people's view towards reality is a difficult but much needed change to wish for.
