Analyst Assessment

Verdict
Even

Neither nation possesses the expeditionary logistics to decisively defeat the other; a conflict would quickly devolve into a low-intensity maritime standoff constrained by mutual economic vulnerabilities.

Wildcards
  • Geography The sheer distance between the two nations heavily nullifies ground force capabilities, forcing any conflict into a purely naval and aerospace domain where neither has robust refueling/resupply infrastructure.
  • Logistical Bottlenecks Peru’s diverse mix of Soviet, French, and Asian equipment creates severe maintenance challenges compared to Argentina’s ongoing and streamlined NATO standardization.
  • Economic Volatility Argentina’s persistent fiscal crises could abruptly halt operational readiness and fuel procurement, limiting its ability to sustain high-intensity operations over extended periods.
