Rally around All the Flags: The effect of military casualties on incumbent popularity in ten countries 1990-2014

Studies analyzing the popularity of American presidents consistently find that even though casualties drag down approval rates over time, there is a temporarily positive effect in the beginning of the mission (also known as the rally effect). Are these findings generalizable to other advanced industrial Western democracies?
