Germany - Deutschland, but in English

Okay, you are correct in that a proper investigation in such a scenario is required. But there is leeway in:

1. prioritizing crimes to investigate - a LOT more damage was done - upwards of 30 billions of German taxpayer money, and this shit is ongoing, with the Cum-Cum / Cum-Ex tax evasion schemes and the involvement of our previous chancellor in it. Those fuckers are still walking without handcuffs
2. how to deal with the outcome of an investigation. German courts can determine guilt, but only the German government can request an extradition. And if there's no money to be had from the individual to be extradited, then they might as well say "we stand with Ukraine, and while we would have appreciated this could have been handled differently, we recognize Ukraine's right to defend themselves". Northstream investors and insurers can be compensated for actual losses (not for non-materialized gains if it can be avoided, that's another way of theft) from tax money for all I care - as a taxpayer.
