If you own the media then you can sit back and relax. At most you'll get few days of moaning and things will go back to normal. Majority of people won't even know or connect things anyway. If media are licensed, then they will never run anything that will upset government too much. I've seen this many times. Even if hostile nation's media pick up the topic and report it honestly, the government can dismiss it as a conspiracy theory or just say it is an attack. Ultimately even if people see all the evidence, most of the time they'll pretend they didn't and stick with the status quo.
