Anarchist anti-nationalist Philhellinism

Here, I want to collect pieces of political thought which try to develop and merge into an unified approach to develop and strengthen German-Greek international anarchist networking to aid in large-scale resisting of upcoming predictable fascist tendencies, particularly in German society, while also addressing spill-over and cross-contamination effects between German and Greek societies and political structures.

I should also mention where each part of this comes from:
Philhellinism
I have a strong connection to Greek culture, and believe this can be leveraged to improve the political developments in both regions.
Anti-nationalism
Past philhellinism was for a very long time extremely nationalist, and, worst of all, was used as justification of many massacres. Additionally, this is important to avoid the mistake of the "Antideutsche" (just with Greece instead of Israel), which tend to ignore most of the catastrophic developments in the favored country, effectively pairing a sort of anti-nationalism in one country with nationalism in another one. Therefore, unconditional anti-nationalism is necessary.
Anarchism
Across all contemporary political ideologies, anarchism appears to be almost the only one that continually remains optimistic and productive even in the face of massive challenges (like the current rise of fascism in Germany and surrounding countries). Most others have stopped offering anything that could still be called an utopia, and general political outlook appears pretty close to nihilism and a disbelief even in the ability to preserve the status quo (except for luxories), let alone improve upon it.
