Considering that 100 years ago the people in Western Ukraine didn't consider that they lived in Ukraine, which they considered to be on the other side of the Dnieper, it wouldn't take much for them to relearn their history.
That's revisionist bollocks, to be frank.
Western Ukraine was always the heart of Ukrainian nationalism, which is why Poland (and Austria) did so much to keep a lid on it. Suggesting that they should 'relearn history' is straight out of the book of fascism.
People standing in the long lines at the Polish consulate certainly do.
That's economic and nothing to do with national identity.
Pre-WWII Western Ukraine, including the Soviet side, was much more Polish before Stalin started sending "Poles" to the gulag.
That's a nice bit of revisionism. In fact, it was a very mixed place. Stanisławów Voivoidship for instance - Poles only made up around 20% of the population. A quick look shows that self-declared Ukrainian speakers were just short of a majority in that province.
Much of the Ukrainian nationalism is pushed by the ruling oligarchs.
Hahahaha. That's a nice attempt at revisionism, but the oligarchs were never particularly interested in Ukrainian nationalism. The current President is the first one, really.
As Ukraine collapses economically and possibly politically, look for Western Ukraine to look for integration with Poland.
That's just not going to happen. Ukrainians would rather starve than let Poles anywhere near them again.
