Gillo Pontocorvo's The Battle of Algiers (1966) is a historical drama about how the French completely failed to win the Hearts and Minds of the Algerians, a people they'd been colonial oppressors to for centuries. Can't imagine why it didn't work.
In 2003 the US Department of Defense held a screening of the film in the hopes of learning something they could use during Operation Enduring Freedom, since they'd failed to learn anything from 60 years of their own military actions. Doesn't seemed to have worked for them, either.
So let me spell it out for you, from colonialism to occupation to, heck, police interactions with Americans, when confronted with people who do not want you around: leaving is an option. Actually probably the best option. The "fight or flight" response includes the flight option, and that doesn't mean flying in reinforcements that will needlessly escalate the situation.
