The U.S. military is unparalleled in "decisive operations" (Phase 3) but consistently fails at long-term stabilization (Phase 4). To succeed, strategy should be reverse-engineered from the desired post-conflict state, rather than focusing solely on winning the initial battle.

The conflict pitted methodical engineer Sir Robert Napier against the emotionally volatile Emperor Theodros. Napier's calm, systematic planning contrasted with Theodros's manic mood swings and confusing speeches to his army, demonstrating how process and stability can triumph over unpredictable passion in a crisis.

When a leader initiates a conflict, an exit that leaves the situation worse than before is politically untenable. This dynamic creates immense pressure to avoid withdrawal and instead escalate involvement, as backing out becomes "political suicide."

Defining success as an ambitious, all-or-nothing outcome like 'regime change' is a critical mistake. Instead, administrations should set clear, measurable military objectives, such as degrading missile capabilities or naval threats. This allows them to define success, declare victory, and create a clear off-ramp for military campaigns.

Initial military actions, like successful bombings, can feel like victories. However, they often fail to solve the core political issue, trapping leaders into escalating the conflict further to achieve the original strategic goal, as they don't want to accept failure.

Nations like the US and USSR prolong involvement in failed conflicts like Afghanistan primarily due to "reputational risk." The goal shifts from achieving the original mission to avoiding the perception of failure, creating an endless commitment where objectives continually morph.

The British Abyssinian campaign succeeded due to its obsessive focus on logistics, from building piers and railways to securing supplies. Commander Sir Robert Napier, an engineer, planned backwards from the objective, demonstrating that operational success hinges on mastering the supply chain.

Despite their military superiority, the British success depended on diplomat Robert Napier securing the cooperation of a local warlord. By showing respect and offering incentives, Napier ensured safe passage and vital supplies, highlighting the critical importance of diplomacy alongside military might.

The core weakness of U.S. foreign intervention isn't a lack of military or economic power, but a lack of seriousness about the aftermath. The U.S. lacks the patience, humility, and stamina for the difficult, unglamorous work of post-conflict planning and nation-building, dooming interventions to failure.
