It is laughable to blame Russia for internal issues in Germany. It was Merkel who invited the Syrians and Iraqis to come to Germany. She was hoping for a Nobel Peace prize... but unfortunately someone else won it. Now I don't understand Russia's role here.
Russia is not directly responsible for situation in Germany, but they are playing very ''dirty'' game in Syria, with their ''friend'' Assad.
It's obvious that, as result of such Russian policy in Syria, to eliminate any opposition to Assad, many people had to escape from Syria to Turkey, and further to Europe.
I think that Merkel did something very humanistic and generous, to accept and help all this refuges, and give them new chance for life.
Don't forget that behind most terrorist attacks in Europe are not refugees but second of third generations of Muslims born in Europe.
Is Germany getting near the end?
No!
Germany in history passed even much more difficult time, like in 1918 or 1945 but they survived and became the most influential and powerful European country.
Nobody can break German's will and strong character.
