Edge: Indonesia
In a conventional engagement, Indonesia's modernized maritime and aerial platforms grant it a distinct advantage in securing sea lines of communication, but Iran's overwhelming superiority in ballistic missiles, drones, and asymmetric proxy warfare makes it a far more lethal and unpredictable adversary globally.

Wildcards
- Archipelagic Geography Indonesia's territory spans over 17,000 islands, creating a logistical nightmare for any invading force but forcing its own military to stretch resources thin across vast maritime domain limits.
- Axis of Resistance Iran’s ability to mobilize non-state actors globally allows it to project power, disrupt trade, and stretch an adversary's focus without committing conventional state assets.
- Cyber Warfare Iran's highly developed offensive cyber commands could cripple Indonesia's logistics networks, maritime domain awareness radars, and civilian infrastructure, bypassing geographic distances entirely.
