Hungary will be rolled over by the Islamic EU when it and the rest of Eastern Europe are isolated. Either that or they will be absorbed into Russia which has its own demographic problems.
The EU’s a lot less Islamic than you think. Consider the lack of any Islamic politicians over in Brussels. (The rubber-stamp European Parliament, which meets in Strasbourg, has maybe 24 Muslims in total.) There is still a burgeoning backlash; consider France’s burka ban, which still stands under even socialist Hollande’s government.
