We don't cry about how unfair the Russia invasion is. We deliver weapons and other support because of the invasion.
The USA did not do a coup in the Ukraine. They wouldn't have succeeded and Russia schemed a lot more there in order to try getting their will there. We don't really know what hidden operations were made there, but do you really believe that a majority in the Ukraine supports Russia? If that was the case, they would have lost the war long ago.
If the NATO really promised Russia not to allow countries of the former Warsaw pact or of formar soviet republic in, why don't the Russians have it in written? I doubt that they would be so stupid not to demand that if it really was promised explicitly. Some NATO person said something about NATO plans to some Russian at some time, yawn. That's just hearsay.
Regarding the actions of the USA in the recent decades, that's pretty much what superpowers are expected to do. I'm not in favour of all of them as well, but Russia did the same. However, the USA didn't invade and take territories from other countries to that degree by force since Maxico war... which was in 1846-48. Or since they took the Phillipies away from Spain in 1898. This is happenning in Europe, so European countries are going to react. In Africa, Asia or the middle east... well, that's somewhere else and yes, the USA and Russia got away with it because they were so much stronger than the others. In Ukraine, that seems not to be the case.
I agree that the Ukraine isn't as much as a flawless democracy, but the Russian propaganda about it being full of nazis is a lie. It's not a justification for an invasion at all.
Regarding more nukes, OK, I exaggerated. I don't want us to have them. France already has enough, so we don't need more. However, having less nukes isn't a matter of just a single country or side. It has to happen on all sides I don't think that France or Britain should have less before Russia reduces their 20 times stronger arsenal.
Scholz, Merz, Macron etc. deserving a bullet through their heads in your opinion is so outrageous that I'm not going to address it. It tells enough without commenting it.
Regarding Germany being untrustworthy, that's completely wrong. Germay of today is far away from what happened in WW1 or WW2. Even the AfD is far away, although a few nazis crept into that party, but it might be the case that you aren't much disturbed by that because that party supports a couple of your points. Also, Germany had way more weapons during the cold war. We gave them up later. I could as well say that Norway is the most unreliable country in the world because of people like you, because a couple of Norwegians supported the nazis or perhaps even because of the Vikings 1200 years ago?
