“In 1992 it was all sovereign Russian territory.”
Not quite. Ukraine declared independence in 1991. Every oblast in the country voted to sever ties to Russia.
Before that, it was the Ukrainian Soviet Socialist Republic, on paper an independent nation within the USSR, with the right to leave at any time. Not that the kremlin would ever let that happen before Gorby came along.
“In fact Russia started in Kiev.”
More accurately there was Ukraine before there was Russia.
