Civ - this is often a way for thugs in government to get their ‘forces’ to attack their own citizens - bringing in ‘outsiders’. Iran used this trick some years back when they were concerned local cops wouldn’t be hard enough on student protesters.
Good point. Even if it doesn't start that way, having a disaffected demographic in charge of national defense often works out that way. Iran's mullahcracy has propped itself up by using many thousands of "Palestinians" and other heavily armed Arab trash. Iran also press-ganged refugees from Afghanistan to staunch the bleeding of its unpopular intervention in and occupation of the failed state of Syria.
