During his tenure, Hollande legalised same-sex marriage by passing Bill no. 344, reformed labour laws and credit training programmes, withdrew combat troops present in the Afghanistan military intervention and concluded an EU directive on the protection of animals in laboratory research through a Franco-German contract. Hollande led the country through the January and November 2015 Paris attacks, as well as the 2016 Nice truck attack. He was a leading proponent of EU mandatory migrant quotas and NATO's 2011 military intervention in Libya. He also sent troops to Mali and the Central African Republic with the approval of the UN Security Council in order to stabilise those countries, two operations largely seen as successful. However, his support of the Saudi Arabian-led intervention in Yemen drew controversy among his left-wing electoral base. Under his term, France also became the most toured country in the world and known as a nation of open markets, regulatory efficiency, rule of law and limited governmental intervention.
