Russia already lost this russo-ukrainian war due to the leadership failures of Vladimir Putin 1 day ago. There is no way that russia can recover from this now and it will suffer the consequences from this for years to come.
It's economy was on decline since the annexation of Crimea and now it's on steep decline which is going to cut it off from majority of the world which is going to cause pain and suffering to everyone in russia for years and generations to come.
It's population is on decline since the fall of soviet union and now it will get much worse.
These actions made Vladimir Putin to be known in history as the fascist who destroyed it's country and it's people waging war on a country of it's brothers and sisters.
NATO is defensive alliance that accepted russia as an ally and friend as evident by G8 and invested in it heavily to be able to extract oil (the only thing that russia can reliably sell to sustain itself at this moment) and to have a sustainable economy and prosperous economy.
This all changed since the annexation of Crimea in 2014.
We are not the aggressor on the subject and we didn't choose to be part of this and we should took this action long before Crimea when he invaded georgia and annexed it's territory in 2008 to prevent this bloodshet instead of continueing to on the afganistan occupation. The failures are on both sides and we can either stop the war now and engage in dialog or we will end up in nuclear WW3 which will end up in the destruction of human race.
Russia can always return Crimea and all of the former territory to ukraine _and Georgia_ for us to be open for a dialog to became a friend and ally again which is what everyone in NATO would prefer thus why we worked on accepting russia in NATO before 2014.
Their concerns about oil to sustain it's economy is noted and valid reasoning to panic and invade ukraine who has newly found reserves of oil that threaten russia.
Putin should Instead of waging wars and destruction engage in a dialogue to explore ways to make russia more economically sutainable and prosperous.
The west was always happy to invest in russia to make it more sustainable and economically independent until this relationship was shattered by vladimir putin who now has parts of georgia, holds belarus a hostage with a country that only has oil that it is unable to dig out and sell to sustain itself.
> cut it off from majority of the world which is going to cause pain
Juche is good actually, not bad.
Everything else in your post is based on this premise and is therefore wrong.
