I am not sure where you get your info from. Many people now think that Ukraine is being sold down the river.
The west negotiated an association agreement from 2007 to 2011 which was eventually signed in 2014 and the latest version is 2023, under which Ukraine is basically and fundamentally controlled by the "EU". What was happening with Russia, Crimea, east of Ukraine could have been handled differently by the west.
Peace terms should ensure that Ukraine gets the benefit of the natural resources on their land, do you not think? Some people think that the EU agreement is like some kind of heavy weight preventing peace and a healing of the hatred, do you think that is possible?
Before 2014 over 50 percent of Ukraine trade was with Russia. The EU agreement changed all that. There was no discussion. It was foreseeable that there would be problems do you not think?
Re separatists, what are the sources for what you say? I am not saying you are right or wrong as I don't know but according to VICE the weapons were handed over to eastern Ukraine by western Ukraine in 2014 going against government orders - there is footage of this happening shown, and interviews. Then things got more confrontational and military aid to Ukraine from outside increased, and the sources indicate that eastern Ukraine had weapons taken from battles which were won. According to OSCE, there wasn't much Russian presence in terms of equipment and no military people (other than attending meetings about Minsk etc). Russia was on the face of it pursuing diplomatic solutions until 2022, this seems to be corroborated by the other western leaders involved in the Minsk negotiations. Germany said they were only sitting at Minsk meetings to give them time to build an army (I can provide the source for this if you want - it was from an interview with Merkel). This was presumably about Crimea though this was not expressly stated. Crimea is of huge strategic value commercially and politically. I am not asserting all of this as fact as I don't know - if you have other bonafide sources, or you think I have missed something re OSCE, please do link.
By the way, financiers in the west were getting very excited about the prospect of a global economy up to 2007 - books were being written about it all all over the place - then some economies said that they thought that one economy might not be the best thing for their countries and a balance of power would be better. Quite a lot seems to have changed after this so this might also have been pivotal to decisions made. Again, I am not an expert here so if you have sources which say the opposite please do link.
