More than 200,000 people fled Hungary after Soviet troops brutally put down the country's anticommunist uprising of 1956. Some 80,000 people fled Czechoslovakia after the Soviet-led invasion of 1968 crushed the Prague Spring reform movement. Current public opinion in these countries shows that more than 81 percent of Czechs, 77 percent of Slovaks, and 70 percent of Hungarians oppose immigration from outside the EU.
