My interpretation is that a lot of the "Great Swedeners" became pan-Scandinavists (until they stopped being so during the last third of the 1800s) and after that had a bit of influence over public life and discourse. But broadly speaking I'd say you are right.
Following that, with the unification of Germany into the German Empire, what we got was a brand of thinkers who managed to vicariously adopt Germany's cause as somehow also Sweden's, and so could also again dream of future military glory, if only by hoping to hitch the little Swedish cart to the German juggernaut. That's where the pro-war as a CP ally in Swedish politics and culture around WWI appeared – like Sven Hedin, or Fredrik Böök. It was largely the same formula for those that in WWII argued that Sweden should take part in the German-led war against the USSR. The weakness of it is that it still has this vicarious quality, requiring an adoption of Germany, which wasn't some kind of universal preference with the Swedes.
