What is the democratic peace theory? What are its limitations?

Explanation:

Democratic leaders are forced to accept responsibility for war losses to a voting public;

Publicly accountable statespeople are inclined to establish diplomatic institutions for resolving international tensions;

Democracies are not inclined to view countries with adjacent policy and governing doctrine as hostile;

Democracies tend to possess greater public wealth than other states, and therefore eschew war to preserve infrastructure and resources.
