However both UK and USA are failed states, their extreme capitalism put too much of their population in poverty and without immigration they simply fall on their own weight.
As before they NEED a war to overthought the table and start over. And they have actually created that, it's not a secret, it's written black on white if only you read their publications from RAND to G8. They use a slightly strange vocabulary but it's clear what they state. They call themselves "the international community" or "the civilized world" but it's clear they just mean their fragmented former colonies. The same have happened in the recent past with the Korea war, as it happened their former colonies start to decide it's time to detach a bit, like SK an Japan themselves https://asiatimes.com/2022/08/japan-korea-defy-us-with-big-r... and even New Zealand https://thediplomat.com/2022/07/new-zealand-will-not-join-th... Australia itself suffering the submarines scam the UK and USA essentially have imposed to them ditching modern but limited French subs to exactly nothing since for a decade at least that's what they'll get (less than nothing since they have payed compensation for the late choice) start to falter undecided witch side to take. Only high treason neoliberal government in the EU keep the USA/UK side against their own Citizens interests.
Some in US and UK have already understood that their war is lost and they menace them to go nuclear in that case, see https://www.independent.co.uk/news/uk/politics/liz-truss-nuc... and https://www.dailymail.co.uk/news/article-11110441/Henry-Kiss... but the rest of the world, the BRICS start to unite knowing that it's freedom or death for them. They have all tested the "freedom" neoliberal nazi means, to a point in eastern Europe many would welcome back Soviet Union...
The above are NOT political or ideological positions but simply facts anyone observing with honesty no matter the personal political position can't avoid to see.
Russia may not like a war but Russia needs resources since it wants to be the only store in neighborhood, and unfortunately, Ukraine does have resources. War was not expected outcome of the initial scare tactic but here we are.
