In the last few years, the world has witnessed huge political upheaval such as Donald Trumps election, Britain's exit from the EU, the recent French election and this month's snap election results in the UK. Meanwhile, four decades since its inception, nanotechnology continues to effect an increasingly diverse range of fields and promises to revolutionize further industries. But what are the implications of geopolitics on nanotechnology and how may nanotechnology create societal and geopolitical changes?So far, the US has been the uncontested world leader of nanotechnology, with its National Nanotechnology Initiative (NNI) receiving a federal budget of more than $1.4 billion for 2017, affirming the importance of nanotechnology under the Trump administration. The US recognised the enormous potential of nanotechnology and created the NNI in 2000 to support infrastructure to develop nanotech for the public good and to maximize the coherence of research and development. While President Trump has upset many in the US scientific community through his stance to climate science, it seems that support of nanotechnology will continue in the US.Despite this, numerous European countries, China, South Korea, Thailand, Japan and others are devoting more and more funding to nano research, which will put the role of the US as the world leader in nanoscience to the test. It is clear that nations the world over see the potential of nanotechnology and understand that it will improve play a part in future national security.In the UK, consecutive Conservative governments have put a big emphasis on supporting science and innovation in the UK, stating in their 2015 manifesto an intention to direct further resources towards the Eight Great Technologies among them robotics and nanotechnology where Britain is set to be a global leader. Current British Premier Teresa May, looks likely to carry on this agenda, with recent manifesto claiming, our ambition is for the UK should be the most innovative country in the world. Despite this, Brexit puts millions in grants for nanotechnology scientists and SMEs at risk from the EUs 2020 funding and it is unclear how a potential deal with the DUP in the UK parliament will change science policies in the UK.Across the English Channel, French president Emmanuel Macron has taken up office intent on intensifying efforts to combat climate change inviting U.S. researchers who might be unhappy with Trump to work in France. Although this statement has irritated some French scientists, who say the move raises concerns about their nations commitment to homegrown science, but what effect this will have on nanotechnology in the country remains to be seen. What is clear is Macrons commitment to the environment, which nanotechnology could have a profound effect on, and the potential for collaboration between US and French scientists which can only strengthen nanotechnology in France.Similarly to Macron's invitation to US scientists, in accordance with it's Belt and Road Initiative, China is taking a collaborative approach to nanotechnology. Chinese President Xi Jinping underlined the pursuit of collaboration with other nations through the initiative, expressing in a keynote speech that he seeks more technological cooperation among participating countries."We should pursue innovation-driven
