The word “robust” is working overtime in this article, that’s for sure.
Besides that, I’d argue this article is a nothingburger: Both the minister of defense and the chancellor are SPD (who view more military involvement as bringing more risk). Meanwhile, the FDP-led ministry of finance wants almost every ministry to save money, and are already asking the ministry of exterior and the ministry of developmental aid to cut spending next year. Lindner won’t outright force military spending cuts but he certainly won’t allow increases either. Budget hawkishness trumps military hawkishness in FDP.
The Greens have almost no say in all of this, they hold the ministry of the exterior, which is not really a position of power.
Overall, Germany is going to be as uninvolved and fiscally “prudent” as NATO partners will allow, no matter the thoughts of representatives without real influence (i.e. everyone interviewed for this article).
