What is your source? What is your definition of "contribution"? Military armaments, financial aid, humanitarian aid, % of GDP? I can't find anything anywhere that supports what you claim. As of now, Germany is 12th in total absolute aid provided as a percentage of their GDP. Source.

In terms of absolute aid provided including military, humanitarian and financial, Germany is only 4th, behind the US, the UK and Poland. So, in relative and absolute terms the largest economy in Europe is at best, being miserly. I believe the German people really want to do more. Scholz and his minions are the problem. Why should he do more when the US, UK and Poland will do most of the heavy lifting. Germany is leading from behind. Again.
