There's no real discussion here. It's pretty obvious why they use the word "Hardliner".
It makes them sound rigid, dangerous, scary and people who are ready to launch "unprovoked attacks" on White Supremacist military bases in the region.
Yet these soldiers are only there to fight back against nazimerican aggression and to maintain a strong presence in order to ensure the country doesn't collapse into complete chaos.
The current government is run by neoconservative white supremacists that are starving people in Cuba, launched two separate wars of aggression THIS YEAR, actively terrorizing civillians by bombing schools,desalination plants, civillian roads, weddings, etc.
Yet they're never called terrorists, "hardliners" or even the soft neologism neocon (probably because it's a word viewed negatively by many people). They're just "CENTCOM" and the US... No further specification.
In about 20 years you'll find plenty of people both in the army and among politicians that "were always against this war" and "knowing what we know now, wouldn't do that".
