I doubt it is about politics in 2016, considering the song was released in 2016 and would have been written prior to the key events you mentioned. Claymation is also a very time-consuming process so the production of the video alone would've taken some months at least. The biggest thing however, is that this song almosts mirrors the exact plot of the British horror movie 'the wicker man'. I expect this was the main inspiration for the song and the political tension in the western world at the time of the song's recording and production would have made it an apt time to release it, considering the similar themes in both the movie and the political times
