Germany's defense spending goes back to WWII. Germany for a long time was not even allowed to have much of a military. They are still in recovery mode. While they have a unique and interesting way to keep manning levels up they don't spend a lot money on their military because of past perceptions of their country. With that being said I think the Germans are still a capable military force when talking about their career military members, but most a just filling in. Iceland and the Northern NATO members including Canada who also participates in NORAD really should be larger contributors as they benefit the most, as well as Turkey.
