Poland and Hungary already have the headache on a border with what's going on in Kiev. I'm wondering if those two countries might actually stand up to the EU. If their leaders can't be bought off, like has happened in so many EU countries.
The EU might buy off the “current” elected leaders of Poland, but they can’t buy off the Polish people.
Read “NO GREATER ALLY” by Kenneth K. Koskodan.
The Poles have a very long history of this sort of thing and a real tendency to remember and get even.
