The US stock market is currently at a historic high, but a potential "diplomatic crash" could occur due to the Trump presidency's acceleration of a multipolar world. This could devalue diplomatic investments made by countries, such as the "special relationship" between the UK and the US, which may be at a historic low. Ireland may also suffer a diplomatic crash due to the potential ineffectiveness of the UN in dispute resolution and the changing geopolitical landscape in the Middle East. A market crash in finance can cause investors to become risk averse and retreat to safe assets, which may also happen in diplomacy, leading to a less engaged diplomatic world and a disregard for international law.
