Security Threats from Inside: Scenario "Extremism in Being and Coexistence with Romany Ethnic Group and Migrants" by PhDr. Antonín Rašek.
At first, we are familiarised with terms of extremism, Romanies (Gypsies), anarchists, neo-Nazis, then the author introduces possible picture of security situation at the turn of second and third decades of 21st century. He believes that in every country there is a limited ability to integrate ethnic groups by majority.
As soon as the limits are exceeded, problems begin. His scenario ends with a pessimistic vision: increasing tensions will ask army deployment, but even local armed forces are not able to enforce law and order, therefore the government must ask for help neighbouring states.
