According to Eerdmans, the name JA21 does not only refer to the first names of himself and Nanninga; it also stands for the 'Right Answer/Correct Answer' (het 'Juiste Antwoord') and 'Your Alternative' ('Jouw Alternatief').[31]
On 20 December 2020, ex-Forum for Democracy MEPsDerk Jan Eppink, Rob Roos and Rob Rooken announced that they had become members of JA21.[32] Two days later, the independent Senate groupFractie-Van Pareren – consisting of seven ex-Forum for Democracy senators – joined JA21, making it the fourth largest party in the Senate.[27][33]
On 16 January 2021, the provincial group of Forum for Democracy in North Brabant split, with three members leaving Forum for Democracy to form the JA21 parliamentary group in the Provincial Council of North Brabant.[34] As Forum for Democracy was part of the province's coalition government at the time of the split, the new JA21 parliamentary group immediately entered the coalition after talks with the other coalition members.[35] This marked the first time that JA21 entered a coalition with other parties.
Ideology
In its platform, JA21 describes itself as both liberal and conservative with an emphasis on personal freedom, political transparency and reliable government.[36] Initially, JA21 sought to emulate the original political platform of the Forum for Democracy party from which it split. Both political observers and the party's leadership have also referred to JA21 as being more influenced by Fortuynism, the ideology espoused by assassinated Dutch politician Pim Fortuyn and his Pim Fortuyn List (LPF) party. Party leader Joost Eerdmans, himself a former LPF member of parliament, has claimed that he wants JA21 to help "Fortuyn's ideas return to the House of Representatives."[7]
JA21 states that it stands for "less regulatory burden, tax relief, a strict immigration policy and support for the entrepreneurs who make our country great".[37] The party is strongly opposed to further integration within the European Union and the EU becoming a Federal Superstate. JA21 wants to strengthen the Netherlands' autonomy by ending influence of the EU on domestic affairs by putting "Dutch interests first" and supporting the right to national self-determination.[37] It also supports a referendum on Dutch membership of the Eurozone, a revision of Dutch membership of EU treaties and the Schengen Agreement, and a renegotiation of Dutch membership of the EU. JA21 is also opposed to the potential accession of Turkey to the European Union.[38] The party also wants to opt out of the EU asylum pact, regain full control over Dutch borders and expel illegal immigrants.[39] JA21 also opposes cuts to the police budget and calls for tougher prison sentences against those who attack emergency workers and repeatedly offend.[40] It also calls for compulsory measures for immigrants to learn Dutch, wants an end to foreign funding of mosques and Islamic schools, and states that people with dual nationality should be stripped of their Dutch citizenship if they join a foreign terrorist group.[41] The party also supports foreign investment and maintaining free trade agreements with other nations in order to stem flows of migration and wants good relations with the United Kingdom following Brexit.[42] JA21 also supports internet freedom and wants to protect the right to online privacy by preventing the government and big tech companies from mining personal data or breaching privacy laws. In terms of culture, the party has expressed opposition to modern architecture and supports restoring historic buildings to their original specifications. In 2022, JA21 campaigned against "de-colonisation" of Dutch history, instead arguing for the protection of national cultural heritage and for free museum admission for Dutch nationals.[43] JA21 is also strongly pro-Israel and following the outbreak of the 2023 Israel-Hamas war and attacks on Israel called for those who support Hamas to be expelled from the Netherlands or prosecuted under Article 131 of the Dutch Criminal Code.[44]
