波蘭與東翼 → 北約與東翼

摘要

Acceded on 12 March 1999 in the first post-Cold-War enlargement, together with Czechia, Hungary and Poland. 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. Poland hosts a United States-led battlegroup and the seats of two multinational headquarters. 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

• Poland shares the rotational lead of Joint Force Command Brunssum with Germany under the February 2026 redistribution; the effective date is not published.
• The United States’ March 2026 posture testimony quotes Polish defence spending of 4.5% of GDP for 2025 and a 5% pledge for 2026. That is a US statement about an ally and is recorded as such; no national percentage is carried as a fact in this module until NATO’s own table has been read.
• Poland’s defence hosts served no force-structure page to this project, so the Polish contribution to the flank beyond the published headquarters and hosting is not carried.
