The USSR's successor [[Russia]] and some other post-Soviet states joined the [[Collective Security Treaty Organization]] (CSTO) in 1992, and the [[Shanghai Five]] in 1996, which was renamed the [[Shanghai Cooperation Organisation]] (SCO) after [[Uzbekistan]]'s addition in 2001.<ref>{{Cite journal |last=Sahai |first=Kajari |date=2002 |title=Declaration of the Shanghai Cooperation Organisation |url=http://journals.sagepub.com/doi/10.1177/000944550203800118 |journal=[[China Report]] |language=en |volume=38 |issue=1 |pages=129–132 |doi=10.1177/000944550203800118 |issn=0009-4455}}</ref>

In November 2005, the Polish government opened its Warsaw Treaty archives to the [[Institute of National Remembrance]], which published some 1,300 declassified documents in January 2006, yet the Polish government reserved publication of 100 documents, pending their military declassification. Eventually, 30 of the reserved 100 documents were published; 70 remained secret and unpublished. Among the documents published was the Warsaw Treaty's nuclear war plan, ''[[Seven Days to the River Rhine]]'' – a short, swift invasion and capture of Austria, Denmark, Germany, and the Netherlands east of the Rhine, using [[nuclear weapon]]s after a supposed NATO first strike.<ref>{{cite news |first=Nicholas |last=Watt |author-link=Nicholas Watt|url=https://www.theguardian.com/world/2005/nov/26/russia.poland#article_continue |title=Poland risks Russia's wrath with Soviet nuclear attack map |newspaper =[[The Guardian]] |date=26 November 2005 |access-date=14 June 2013}}</ref><ref>{{cite web|url=https://css.ethz.ch/content/specialinterest/gess/cis/center-for-securities-studies/en/services/digital-library/articles/article.html/107840|title=Poland reveals Warsaw Pact war plans|publisher=[[International Relations and Security Network]]|access-date=23 December 2014|archive-date=9 July 2021|archive-url=https://web.archive.org/web/20210709183149/https://css.ethz.ch/content/specialinterest/gess/cis/center-for-securities-studies/en/services/digital-library/articles/article.html/107840|url-status=dead}}</ref>
