Liberty Splits: USMCA 2026 Drift, National Security Failure, and the Cost of Delay is a near-future geopolitical thriller set where nothing collapses - and everything quietly comes apart. In 2026, the mandatory review window of the United States-Mexico-Canada Agreement (USMCA) arrives. Markets notice. Washington recalculates. Canada hesitates then delays. By 2035, the consequences of delay are no longer theoretical. As North America hardens its trade, security, and industrial posture, Canada finds itself trapped between rhetoric and reality. Supply chains fray without breaking. Capital doesn't flee - it simply stops arriving. Institutions continue to function, but with diminishing authority. The country adapts to drift rather than correcting it. Toronto analyst Joel McCay watches the signals accumulate. His former partner Maya Khan, now advising from Brussels, sees the divergence earlier - and more clearly. In Boston, engineer Lucas Harding helps develop SIGMA, an advanced embodied AI designed to surface trade-offs without sentiment. SIGMA does not predict collapse. It documents erosion. What emerges is not a crisis, but something more dangerous: normalization. Liberty Splits explores how a capable, well-intentioned society can lose leverage without losing stability - and why the USMCA 2026 review becomes a structural fault line rather than a moment of renewal. No villains. No coups. No panic. Just decisions postponed long enough that choice itself begins to narrow. This is not a story about hostility between allies. It is about asymmetry - of urgency, of incentives, of timelines. About how national security failures can occur without a single dramatic act. About how trade agreements matter most not when they are signed, but when they are tested. Written in a cold, procedural style with intimate human vignettes, Liberty Splits is a realistic warning set inside a plausible future - one that asks a single unsettling question: What happens when a country waits too long to decide - and the world decides for it?
