Analyst Assessment
Verdict
Edge: Nigeria
Nigeria holds an insurmountable conventional, technological, and numerical advantage, but projecting that power into Mauritania's extreme geography would severely strain its logistics and exploit its internal security overstretch.

Wildcards
- Geographic Depth Mauritania's vast, under-populated desert provides immense defensive depth, severely complicating the sustainment and logistics of any invading heavy mechanized force.
- Domestic Overstretch The Nigerian military is heavily deployed across all 36 of its own states for internal security; sustaining an expeditionary campaign risks critical domestic security vacuums.
- External Alliances Mauritania's integration with NATO's Mediterranean Dialogue and Czech defense partnerships could prompt rapid Western intelligence sharing and ISR support to offset Nigerian advantages.
