I don’t believe these stories about Russia believing they would win the war in 1 to 3 days. That is just ridiculous.
Ukraine and Texas are as good as equal in land mass. Ukraine's population is 40million to Texas' 30million. If Texas were an independent republic that Biden wanted to take, I can't imagine it being subdued in six months.
I don't know what Putin expected or is expecting. I don't trust anything in the news from either side about it.
