It begins as France starts the expulsions:

France expelled nearly 100 Gypsies, or Roma, to their native Romania on Thursday as part of a very public effort by conservative President Nicolas Sarkozy to dismantle Roma camps and sweep them out of the country, the Immigration Ministry said.

This is why I have never bought into the notion that the European nations are going to disappear due to their demographic issues. They are reacting much more strongly to a much lower percentage of the population than Americans have with Hispanics because they have no “melting pot” mythology. Notice that with the economic contraction, the assumption that Turkey would join the EU has faded away. Demographics are destiny, but they do not always proceed in a clean and linear fashion.
