Korean War can be viewed North Korea as a separate country attacking South Korea, or a civil war. But, Vietnam war (including invasion of Cambodia) and a host of South American wars where much more clearly started as civil wars with Forein support not really invasions.
PS: Afghanistan is something of a wash with the US also invading the country.
