Contents of the United States diplomatic cables leak has depicted Europe and related subjects extensively. The leak, which began on 28 November 2010, occurred when the website of WikiLeaks—an international new media non-profit organisation that publishes submissions of otherwise unavailable documents from anonymous news sources and news leaks—started to publish classified documents of detailed correspondence—diplomatic cables—between the United States Department of State and its diplomatic missions around the world.

Albania Guantanamo Bay detainees

After accepting five Uighur detainees from Guantánamo Bay in 2006, Sali Berisha offered to take three to six detainees extra. American diplomats portrayed his offer as "gracious, but probably extravagant... as always, the Albanians are willing to go the extra mile to assist with one of our key foreign policy priorities".

Austria Foreign policy

U.S. diplomats criticised the Austrian government—and especially Austria Chancellor Werner Faymann, and minister of defence Norbert Darabos—for the lack of interest in foreign policy. Foreign minister Michael Spindelegger is criticised for only caring about the expansion of the Austrian economy.

Secret business deals with North Korea and Iran

Further contacts between Austrian banks and Iran and North Korea are criticised. Austrian companies supplied Iran with high-tech equipment for its nuclear program. At the same time government officials helped disclose the deals by secretly passing on that information to the U.S. embassy.

Baltic countries Operation Eagle Guardian

The three Baltic countries, Estonia, Latvia and Lithuania, have been added to Poland as countries to be defended from Russia. Such plans by the U.S. and NATO were revealed by the leak of a confidential cable from U.S. Secretary of State Hillary Clinton in January 2010 that allegedly stated that this expansion of pre-existing contingency plans, known as Operation Eagle Guardian, had been approved by NATO allies. This would specifically involve American, British, German and Polish NATO divisions. The cable also warned against public discussion of the military plans for fears of unneeded increase of NATO-Russia tensions. According to Russian foreign ministry sources they were "perplexed" to learn of these plans.

Belgium Defense

Mails from the American embassy in Brussels reveal that Minister of Defence Pieter De Crem is considered by the U.S. as their best supporter in the Belgian government, unlike prime minister Yves Leterme or Johan Vande Lanotte. De Crem also asked Hillary Clinton to insist with the Belgian government for more funds for the Belgian army.Pieter De Crem is vriend van Amerika, www.standaard.be (in Dutch), January 29, 2011 The U.S. was also concerned about plans for the removal of all nuclear weapons in Kleine Brogel, but the Cabinet of De Crem reassured the Americans that these plans would be stopped in Parliament.België neemt deel aan de Navo-kernmacht, www.standaard.be (in Dutch), January 29, 2011

Bulgaria Soccer clubs owned by the Mafia

According to a cable from the U.S. Ambassador to Bulgaria from January 2010 Bulgarian soccer clubs are widely believed "to be directly or indirectly controlled by organized crime figures who use their teams as a way to legitimize themselves, launder money, and make a fast buck." The cable further notes that due to very few arrests and successful prosecutions the public has lost faith in the legitimacy of the league and stopped watching the games.

Croatia S-300 missile

A cable written by the U.S. Ambassador to Croatia Ralph Frank in November 2003 reveals the American interest in obtaining the S-300 surface-to-air missile system from Croatia. The Croatian government acquired the system in 1995, before the Operation Storm, but it was incomplete and was never operative. According to other sources, including the court testimony of arms dealer Zvonko Zubak, the system was indeed shipped to the U.S. in 2004.

Germany Data sharing

A number of cables from the U.S. embassy in Berlin reveal the U.S. concern on Germany's position in the SWIFT-, TFTP- and the bilateral U.S.–Germany data sharing agreement. A revealing cable from December 2009 (09BERLIN1528) describes how German Minister of the Interior Thomas de Maizière overruled Justice Minister Sabine Leutheusser-Schnarrenberger and abstained from voting at the November 30 Committee of Permanent Representatives vote in Brussels on an interim U.S.–EU agreement to continue the Terrorist Finance Tracking Program (TFTP).

Guido Westerwelle

U.S. embassy personnel were very critical of German foreign minister Guido Westerwelle. American diplomats have criticized his ineffectiveness, stating that "he's no Genscher". An embassy cable sent from Berlin on 22 September 2009 describes Westerwelle as having an "exuberant personality" and calling him an "enigma" who "remains sceptical about the US".

Khalid El-Masri

American officials warned Germany in 2007 not to enforce arrest warrants for CIA officers involved in a bungled operation in which Khalid El-Masri, an innocent German citizen with the same name as a suspected militant, was mistakenly kidnapped and held for months in Afghanistan.

Ireland Shannon Airport and the United States armed forces

A 2006 memo on Ireland featured when on 1 December 2010 it was revealed that American diplomats discussed the Irish government's attempts to oppose American military use of Shannon Airport before Ireland's 2007 general election. After this release Amnesty International asked the Irish government to tighten its legislation to control the use of Irish airspace by the Americans. Colm O'Gorman, the organisation's executive director in Ireland, observed that concerns expressed by Irish citizens over the misuse of the airport by the Americans was "a problem to be managed rather than something to be taken seriously".

According to a 2006 diplomatic cable sent from the U.S. embassy in Ireland, "the Irish Government has informally begun to place constraints on US military transits" at Shannon Airport. The Irish government attempted to limit the transfer of weapons from the U.S. to Israel via the Shannon Airport. James C. Kenny, U.S. Ambassador to Ireland at the time, said Irish officials were warned that the U.S. would use other airports if the policy continued.

Murphy Report

The Vatican stated that another leak of a February 2010 cable was "an act of extreme seriousness". The leak revealed that the Vatican had not replied to questions from the Commission that compiled the 2009 Murphy Report on the Sexual abuse scandal in the Catholic archdiocese of Dublin because it felt that such questions should be forwarded only through diplomatic channels.Staff writer (13 December 2010).

Retrieved 15 December 2010. The Murphy Commission had written to Pope Benedict XVI as head of the Roman Catholic Church, and not as a Head of State, and the lack of any reply indicated to it that the Church was continuing to hide relevant facts behind the sovereignty of the Vatican City. Commenting to the press after its release, the Vatican said, "Naturally these reports reflect the perceptions and opinions of the people who wrote them, and cannot be considered as expressions of the Holy See itself, nor as exact quotations of the words of its officials".

Gerry Adams

A cable sent from Dublin suggested that the Irish Government had "rock solid evidence" that Gerry Adams was a member of the IRA military command structure, and Bertie Ahern believes Adams had advance knowledge of the 2004 Northern Bank robbery; claims that Mr Adams has continually denied.Moriarty, Gerry (14 December 2010).
