[ATL] Transatlantic

ATL | Transatlantic is the theatre of the one relationship European defence still hinges on — the United States as supplier, enabler, and constraint. From FMS approvals, technology-release and export controls to force-posture withdrawals, burden-sharing pressure, and the reliability of the American guarantee — and how Europe answers each. Distinct from the NATO & EU theatre [INT]: this is specifically the US–Europe axis.
