Why Germany's far right is on the rise?

For the first time since the 1930s, the far right is on the verge of a national electoral breakthrough in Germany. February’s snap parliamentary election is looming, with the opinion polls putting the Alternative for Germany (AfD) party second with about 18-20 percent. The AfD is anti-immigration, anti-European Union, often pro-Putin and is being monitored by German intelligence agencies. Could dissatisfaction with mainstream politics and economic stagnation thrust a German far-right party into real power for the first time since World War II? Most parties rule out power-sharing with the AfD. More than 100 MPs support a move to ban the AfD for "extremism". But how long will the party be ostracised if it continues to surge in nationwide popularity?
