The United States' membership of NATO, in force since 4 April 1949 as a founding signatory. Membership is a treaty fact rather than an assessment of alignment. The United States frames the battlegroup in Poland and has held the SACEUR appointment continuously.
NATO and the eastern flank has as a member The United States and the eastern flank. A directional arrangement: the two parties do not hold the same position in it. Authored once and read from both ends.
安排
- 狀態
- 進行中有效且正在運作。不涉及其運作成效，也不涉及其走向。

- 國防機構法律與條約經記錄此安排所包含的類別。並非衡量指標：涵蓋較多類別的關係只是描述得更詳細，而非更為牢固。
摘要
One of the twelve states that signed the North Atlantic Treaty in Washington on 4 April 1949, so its membership is not an accession but the treaty itself. Membership carries the mutual-defence commitment of Article 5 of the North Atlantic Treaty, under which an armed attack against one ally is treated as an attack against them all. The United States frames the battlegroup in Poland and has held the Supreme Allied Commander Europe appointment continuously. This record states the membership and its date; it says nothing about how much this state spends, what it contributes, or how reliable any party considers it — none of which membership establishes.
為何重要
成員國組合是本模組的骨幹：戰區內的每一項前沿部署、每一項指揮安排與每一項增援計畫之所以存在，都取決於誰在此條約之內、誰不在其中。按順序閱讀加入日期，也能解釋戰區的樣貌——於1999年與2004年加入的國家，正是如今前沿存在所在之處，而最新加入的兩個國家則補齊了波羅的海與北部陸地邊界。
協議
- 《北大西洋公約》 · 簽署於1949-04-04
創始條約。第5條載明共同防禦承諾；第10條是加入條款，之後的每一個成員國都依此加入。
仍然未知的事項
- The United States’ March 2026 posture testimony states that Europe must assume primary responsibility for its own conventional defence while the United States remains committed to Article 5 and to NATO; that is a stated position, carried on the actor’s posture block, and membership does not grade it.
- US force levels in Europe are not carried anywhere in this module from a source read; the SACEUR appointment’s continuity is the one contribution fact membership establishes.
