The Dutch and Danes have so little troubles ... life as government would be boring without overseas adventures, I guess.
The Poles clearly do it for bargaining.

There ARE reasons for those missions, I just don't approve them.

And as a proponent of more basic and less parliamentary democracy: The Swiss do very fine with it. The fears about it were proved to be wrong on many occasions.
Anyway - a citizen majority against the mission in Afghanistan impresses me more than the generally despised "Germany is being defended at the Hindukusch" of former defence minister Struck.

The whole expeditionary stuff would be less worrying if we had demonstrated the ability to deploy at least one of our three divisions fully to the new Eastern NATO border on short notice and sustain it during some weeks of exercises.
Such basic collective defense skills were afaik never demonstrated.
