In cases like South Africa, where security forces are unlikely to defect, the business and corporate elite become the linchpin for change. A combination of boycotts, strikes, and international divestment pressured the business class, which in turn pressured the pro-apartheid party to reform, leading to a democratic transition without a civil war.

Contrary to movie portrayals, real political change rarely happens in a single, dramatic moment. It's a slow, arduous 'movement' that requires sustained participation within existing institutions. Lasting impact comes from changing the system from the inside, not from being an external disruptor.

The most potent threat to an authoritarian regime comes not from visible dissidents, who are often neutralized, but from patriotic loyalists within the system. These insiders believe the current leadership is corrupt and harming the country, making their patriotism a powerful tool that can be turned against the regime.

Computational studies reveal that simply mobilizing large crowds is the least likely strategy to succeed. A more effective approach, an "informed pillar strategy," involves identifying and targeting the opponent's wavering pillars of support (like business or security elites) to create a cascade of defections.

Citing Gandhi and the Civil Rights Movement, the most successful long-term protest strategies rely on peaceful non-resistance. Active resistance, even when justified, often escalates violence and cedes the moral high ground, making it a less effective tool for systemic change compared to disciplined, peaceful protest.

Dictatorships can tolerate individual criticism but actively suppress mechanisms that create common knowledge, like public assemblies or organized online groups. They understand that power rests on preventing citizens from realizing that their grievances are shared. Once dissent becomes common knowledge, coordinated revolt is possible, which no regime can withstand.

Jane Fonda argues that defeating an authoritarian regime requires weakening its "pillars of support" like finance, military, and art. This is achieved through strategic noncompliance—strikes, boycotts, and mass actions that hit the economy—rather than traditional protests, which are less effective against entrenched power.

Effective activism doesn't try to persuade politicians or stage a revolution. Instead, it should 'inject a retrovirus': build and run privately-funded alternative institutions (like citizens' assemblies) that operate on a different logic. By demonstrating a better way of doing things, this strategy creates demand and allows new institutional 'DNA' to spread organically.

Research synthesizes four crucial elements for successful movements: 1) large, diverse, and growing participation; 2) securing defections from the opponent's key supporters (e.g., business or security elites); 3) tactical flexibility, shifting between protest, non-cooperation, and building alternative institutions; and 4) maintaining nonviolent discipline, even under repression.
