Prologos, there was very simple problem with it, which is population count. Czech Republic is still having less population than it had in the peak of 1940 when it stood to 11.1 millions. Today, there is 10.6 million people. West Bohemia is not fertile land, it is actually climatically the harshest region in the country where frost can appear throughout the year, even in the peak of summer when temperature in the Prague and Moravian valleys are close to 36C. West Bohemia was not repopulated, because it was military zone between two different political systems until 1990. Back then you cannot even travel to counties bordering with West Germany without permit, less to live for 45 years. This military zone affected even non-Sudetenland counties like Domazlice/Taus which are across to Bavaria, but were never part of Sudetenland and were Protectorate during WWII.
It is not responsibility of the Czech Republic to host these hordes of refugees. They do not want to stay there anyway. When I was in Prague 10 days ago, the refugees were rioting all over in the refugee camps demanding to get into Germany. Police and military units were called twice there. In Slovakia, widespread refugee riots occurred two weeks ago and had to be subdued by military means. Slovakia solves the issues more harshly than the Czech Republic. The government and population wants to get rid of them the fastest way it possible, dump them at the German borders and prevent any influx going on. Yesterday, the Czech military is considering to seal the borders totally, and Hungarian is already doing it. Winter is approaching, and once November settles in, the deep freeze will arrive when temperature drops to -20C.
