Polish activists arrested?...Maybe 'Polish agitators' or 'Polish activists paid by Khazar agitators'.
No, not polish agitators. Polish minority living there for hundreds of years. They had a dozen or so "Polish houses" partially financed by Poland few years ago. Nothing fancy, that much we owe them. Anyway it was seized by Belarusian authorities by seizing Polish organization first. It has nothing to do with words like imperialism, revisionism, etc. It is simple issue of minority rights which are abused by dictatorship authorities. Belarusan opposition as far as I know defends Polish minority.
