One similarity between the Korean War and the Vietnam War is that: both wars resulted in the establishment of successful democratic governments.

both wars involved the Soviet Union, Great Britain, and Germany.

the U. S. was victorious in both wars.

neither war had a clear winner.

Hey there!

I'm pretty sure the answer is "Neither had a clear winner."

Hope this helps :)

herodotus taught this. herodotus was an ancient greek historian who was born in halicarnassus in the persian empire. he is known for having written the book the histories, a detailed record of his "inquiry" on the origins of the greco-persian wars.
