when you bailed your own banks
German banks were significantly less exposed than the French ones. And even then, the country that mostly benefited from those bail-outs were Greece. Without them, they would have been forced out of the Euro, a possibility so bad that Tsipras ultimately balked when his renegade finance minister tried to talk him into it. The Greek people thought the same, they just took issue with the idea of having to reform their state into anything resembling modern Western standards. They did not have a modern land register (something most European states have been using for 60+ years) but wondered why land owner tax revenue was so low. Their welfare system did not bother to check up when almost an entire small island claimed disability checks. I could go on. Which is fine if paid by the Greek people, but outsiders might be justified to demand some changes before they hand out money.
which knew very well about irregularities
Not true either. It has been a few years since I've read up on this, but I remember reading that some historians doubted if the Greek government itself knew about the true extent of their debt for most of the time.
You might wanna look up that part of European history. Germany (and many others) was initially against Greece joining the Euro, but Athens lobbied and deceived Bruessels about the state of their finances. Perhaps it was made too easy for them, but responsibility firstly lies with the one who deceives, not the one being deceived.
exclusive German idea
I get it, Germany deserves blame for continuing with this policy after Crimea. But let us be real here. Most of Europe bought Russian energy, in many cases more per capita than Germany. And those who did not often acted as money launderer for Putin's oligarchs. Quite a few countries continued to receive Russian energy after the
delivery to Germany ended. Singling out Germany for blame for financing Putin's army is under those circumstances really hypocritical.
To claim Poland as your sphere of influence
This is probably a joke, but do we really need 19th century terminology on such a thread? Is it not enough that with Putin one leader actually still thinks in such terms and makes us Europeans pay for it one way or another?
As for "guaranteeing" Poland's security. There is certainly room for further cooperation. Right now German soldiers are stationed in Poland, helping it protect against Russian rockets. Poland could join the European Sky shield initiative and maybe make some own proposals on how to proceed. The treaty of Aix-la-Chapelle (2019) is a good example to what this can eventual lead to. Sure, this would take time, but who knows how the world looks like in 10-20 years.
