There are many concerns about future American position in the Globalised World. Many foresee China as future superpower. This way opinions of George Friedman, American political scientis might seem strange. In his opinion USA are only at the begining of their supermacy in the World. And because they need allies in strategic points in the world, they will support them. One of such strategic points in the world is Russian - Polish border. Of course if you take into account that countries like Ukraine and Belarus are not fully independent, and Russia's impact there is very deep. On the other hand European Union will rather not cross this border - and the two countries will never become mebers of EU.
You might not agree with such a point of view. First the future of Ukraine is still uncertain. The second, current American economic problems, and economic growth of China cast a shadow on 'Pax Americana'. But there are some interesting points still in my opinion. The most important is the fact of the close relation between Poland's and Russia's power - and the corelation between them. The corelation is simple: the stronger Russia the weaker Poland, and the weaker Russia the stronger Poland. Theoretically the coutnries could coexist peacefully, both being either strong or weak. But the geopolitical structure of Eastern Europe, and lack of other stronger players in the region makes this corelation enedemic for the region.
So if currently Russia is weakening and Poland is becoming stronger and stronger, you might foresee that the process will have long term consequences. The balance of power is changing, and in Friedman's opinion it will involve shifts of borders. Shift of Polish border to the east, to be precise.
