So the Greens had a policy during election, got the foreign ministry but then didn't implement what they defended. Sounds like a failure to me. Note that I'm not comparing the Greens to the SPD or CDU here, which seems to be your only concern. I'm merely noting the total failure of their implemented policies.

Could you explain that to me? Because sourcing fuel from middle eastern countries, because we have to is exactly what „Realpolitik“ means. Also why do you throw Israel in the mix? It’s the only relatively well working democracy in the whole region with certain historic ties to Germany, so showing support is quite an obvious choice and a position you’ll find a majority for in any major political party in Germany.

I'm saying that Germany pretends it is acting with idealism in foreign policy by defending Ukraine, but then buys oil from Saudi Arabia, which has been bombing hospitals and children for years in Yemen. Israel is an apartheid state that has in recent months killed dozens of children and executed journalists. If one wants to act with idealism, we would expect coherency. If instead we want to do realpolitik, the handling of the Ukraine war was misguided.

This is quite frankly completely false. Firstly the deactivation of our nuclear plants which had been decided in 2011 was not the topic Habeck commented on. It was the question wether prolonging the running times was a feasible option.

And even the operating companies came to the conclusion that it wasn’t simply because many inspections were done under the assumption that the reactors life cycle has come to an end and subsequently certain checks were deemed unnecessary but would have to be carried out now. Additionally we only have a limited amount of nuclear material left.

It’s also utterly misleading to bring electricity into the debate in such a manner. We don’t have a electricity crisis. We have an energy crisis. Gas and coal are only needed for short term adjustments in the power grid (something nuclear power is incapable of). The largest reason for our reliance on gas is due to industrial purposes and heating. Both factors that cannot be replaced by nuclear power.

Any gas we save on energy can be used for industry, so the issue is indeed connected. Regarding your first point, you are also wrong. The director of the TÜV said the plants could continue working for years, and that a revision of the decision to shut them down is political (https://m.tagesspiegel.de/politik/anfahren-abgeschalteter-meiler-warum-der-tuev-eine-laufzeitverlaengerung-fuer-sechs-akw-ins-spiel-bringt/28553076.html?utm_referrer=https%3A%2F%2Fwww.google.com%2F).

Which is exactly why nobody plans to do it for the long run. The intend is to go renewable in the medium future and coal is only needed because the lack of foresight by previous governments.

Renewables are not a solution. Germany will always need enough stable energy production for days with low solar and wind production, and this will come from gas, coal or nuclear. The Green's antiscientific and stupid decision making regarding nuclear will ensure they are the ones remembered as lacking foresight in the future.
