Faced with the threat posed by Russia and the US military withdrawal, we Europeans find ourselves in a difficult position: we must consider rearming and, as a result, make tough budget choices. Will Europe ultimately have to choose between defending its social model - and defending itself?

This is the first of three episodes where we're going to take a look at the challenges facing our European societies.

An episode by Hermine Donceel, brought to you by Euranet Plus.
