Military units often used 'red-amber-green' charts that inevitably showed progress during their deployment, regardless of the reality on the ground. This created a cycle of self-reported success that masked the fact that security gains were temporary and territory reverted to enemy control as soon as troops left.

Current military assessments focus on inputs like '6,000 targets struck,' creating a false sense of progress. This echoes the Vietnam War's body count metric, which measures activity but fails to assess actual strategic effects like achieving free navigation or eroding the enemy's power.

The policy of rotating commanders on one-year tours was a critical strategic flaw in Afghanistan. Each new commander arrived believing they had the "recipe for success" and would change the strategy, resulting in a series of disconnected, short-term plans that prevented long-term progress.

When questioned on progress, the Pentagon defaults to 'input metrics' like money invested, avoiding 'output metrics' like the number of missiles produced by a specific date. This focus on process over results allows critical projects to languish for years.

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.

The full quote, often misattributed to Peter Drucker, cautions that our obsession with measurement can lead us to manage pointless metrics, sometimes to the detriment of the organization's actual purpose. This highlights the risk of losing sight of what truly matters.

A Soviet nail factory, first incentivized by the number of nails, produced millions of uselessly tiny nails. When the incentive changed to total weight, they produced uselessly giant nails. This is a classic example of Goodhart's Law: when a measure becomes a target, it ceases to be a good measure.

When complex situations are reduced to a single metric, strategy shifts from achieving the original goal to maximizing the metric itself. During the Vietnam War, using "body counts" as a proxy for success led to military decisions designed to increase casualties, not to win the war.
