28 and 7 years ago, with the 8-year Gulf War 2 starting in between 15 years ago, we got classic case studies of the propaganda model in full effect. From the neutral-by-law BBC to the 'centre-left' Guardian in the UK, and across the US media (and every one of Murdoch's huge global empire of newspapers) government military action in the middle east, launched without UN legal approval, received supportive coverage. Huge public anti-war demonstrations received minimal mainstream coverage.
Chomsky himself has spoken at length on how the (then threatened) attack against Syria fitted his model (easy enough to find from a simple search). The alternative news media paints a very different picture from the mainstream, mass media of the UK, US, French and Israeli bombings.
Here's two contrasting examples, one unpicking the rhetoric of coverage in major US and UK media, the other a piece from The Guardian, whose centre-left readership will be broadly hostile to military action abroad (but seen as persuadable if it's for 'humanitarian' causes), and certainly hostile to the Tory PM who is uncritically quoted at length (source strategies) until the end of the lengthy article when Corbyn's objections are mentioned.
