phenomenon, and that the Government needed to implement measures to reduce human contribution to global warming. Key committed the National Party to working towards reducing greenhouse emissions in New Zealand by 50% within the next fifty years. Commentators note that as late as 2005, Key made statements indicating that he was sceptical of the effects and impact of climate change. As a first-term MP in 2003, Key criticised the Labour-led government's stance on the Invasion of Iraq, claiming that New Zealand was "missing in action" by failing to support its ANZUS allies, the United States and Australia. In August 2007 Key claimed that he would have taken a similar position to Clark and not sent troops to Iraq. In response, the Government argued that his comments from 2003 suggest that Key would have deployed troops had he been Prime Minister at the time. Like his predecessor Helen Clark, Key views a New Zealand republic as "inevitable", although probably not for another decade. "If Australia becomes a republic there is no question it will set off quite an intense debate on this side of the Tasman", he said. "We would have to have a referendum if we wanted to move towards it." Key later stated that he was a monarchist, and that a New Zealand republic would "Not [happen] under my watch". In 2009 Key's government restored titular honours, including knighthoods and damehoods — the abolishment of these titles in 2000 had been seen as an advancement towards republicanism. During the 2020 New Zealand euthanasia referendum, Key publicly expressed support for the End of Life Choice Act 2019, saying that his mother's struggle with Alzheimer's disease prior to her death convinced him to support the decriminalisation of euthanasia. In September 2021, Key criticised the Labour Government's elimination-based lockdown policies in response to the COVID-19 pandemic in New Zealand, likening it to making New Zealand a hermit kingdom like North Korea. He also accused the Government of ruling by fear and lacking a post-lockdown strategy. To speed up COVID-19 vaccination, he recommended boosting funding for Māori and Pasifika health providers, introducing financial incentives for young people, and allowing only vaccinated people into licensed premises. TVNZ journalist Jack Tame described Key's views on the Government's handling of COVID-19 as provocative but praised his five-point plan as a "collection of sensible ideas worthy of consideration." In August 2022, Key described United States Speaker of
