Major Regional Power Military vs Japan Self-Defense Forces: What Decides Invasion?
Most analysis asks who is stronger. Warlord Intel asks who has leverage.
Short answer
An amphibious invasion of Japan represents a catastrophic geopolitical event, instantly drawing in major global powers and shattering the existing international order. The economic shockwaves alone would trigger a global depression, while the risk of direct conflict between nuclear-armed states would elevate to an existential crisis. This scenario would redefine global security parameters for decades.
