Over the last few months there were many attacks around Europe ( France, Belgium, Germany) all those attacks were by extreme Muslim groups.
Europe policy of freely letting refugees in from Muslim countries is biting them in the A**. While I am sure most of those refugees need the help and are innocent there are many terrorists that use that channel to get into Europe and setting up bases, recruiting people to carry out their attacks, brain washing people etc... etc...
Instead of standing strong against those terrorist and the extreme Muslim population Europe caves in time after time and then they wonder why those attacks happening in their back yard...
Here is a classic example from today. Czech Republic today decided to teach kids in their schools that Tel Aviv and not Jerusalem is the capital of Israel... Why do you ask they did that??? Well that is very simple, Extreme Muslim groups do not want to recognize Jerusalem as the capital of Israel so they are forcing people to not mention it in their teaching...
Until Europe takes strong approach to these Muslim Groups they will suffer more and more of these attacks ( unless they just going to roll over) and their economy will suffer... After all most of the refugees that come to Europe move to the western states ( Belgium, France, Germany, Great Britain etc... etc..) to get the free benefit the government is offering them...
