I understand that it's supposed to be a shitty comic and not a balanced, reasonable take, but if you'd like to hear a German perspective anyways:

I'm not aware of any official representative lobbying other countries to end nuclear, except of course in nations that build their totally safe reactors near our border. I'm also not aware of us being awarded or recognized for our stance. Individual Germans, like me, will of course have been fed different propaganda than you and will argue accordingly.

No one here likes the coal generators. And with how much cheaper solar is these days, they're definitely on the way out. But we don't have a dictatorship anymore, luckily, so even obviously good paths will face pushback, like from entire regions whose jobs are in the coal industry.
We've just been able to get a consensus on abolishing nuclear much more quickly for multiple reasons:

• Chernobyl directly affected us, including the people running our country. Russia also attacked nuclear reactors in the Ukraine, which certainly reminded people of Chernobyl.
• At the start of the Ukraine war, it was unclear whether Russia might also launch attacks on us, including our nuclear reactors.
• Russia also cut off our natural gas supply. We have practically no own Uranium deposits either, so reducing dependence on foreign nations was definitely in our interest, too.
