The magic word is credibility.
Disinformation can mean leaving out important informations. Telling lies is not the only method of disinformation. The not telling also creates thoughts and delegates them into certain directions, whereas other models of thinking are left out.
Like this, the deaths on the own side are adjusted downwards whereas the victims of the enemy are counted proudly - as long as they are not civilians. The post-Gulf War period demonstrated how the population reacts if the number of innocent victims is much higher than expected. It was the fact of those numbers that provoked the biggest part of the post-war critique.
The media in democratic states tend to criticize this, which does not mean that they always want to be free of governmental influence. They can choose to help the government in a single case by not writing anything against it or by writing pro-government stories.
At the same time every democracy has undemocratic parts in it - which is already part of democracy itself. There are situations when a democratic government may find it essential to put pressure on the media to inform the population in a certain way; and also censorship is nothing that can only be connected to dictatorship; just think of the Falkland War, the Gulf-War or the Kosovo-War.

In 1948 the former alliance of USA, UK, Canada, Australia an New Zealand established in World War II was formalized into the UKUSA Signals and Intelligence agreement to aim primarily together against the former USSR, although readers of the agreement say, that it is definitely only signed by the United States and Britain. A number of other countries' SIGINT agencies also participate in the UKUSA community, including those of Germany, Japan, Norway, South Korea, and Turkey. These countries are sometimes described as "Third Party" members of the agreement. In addition, some countries, such as China, host UKUSA SIGINT stations or share SIGINT on a more limited basis.
