“Russia is seriously losing a war they started. This should be obvious to everyone now.”
Based upon what measurement(s)?
Who is advancing and taking cities? If an invader supposed to do that, the failure to do so means they have not only stalled but where they have been pushed back means they are losing.
This is especially true when a Nation like Russia is supposed to dominate the Eastern European region. When it cannot do this, it is because it no longer has the strength to do it.
Unless you want to say Russia is not serious about winning?
