Indeed, one would actually expect wartime news to closely reflect government agendas. For one thing, significant deviation might even be perceived as treason. And, in fact, governments have been involved with wartime propaganda since the First World War, whether to manipulate populations at home or to influence those abroad.
For example, in September 1914 a secret organization called Wellington House was established in Britain. Its members included journalists and editors who wrote and disseminated articles and stories favorable to the United Kingdom. And their reports were able to reach international news agencies much faster than the German equivalents because British forces had severed German underwater communication cables.
