At a time of instability it is unity needed, not division
The G20 meets at a time when world peace and stability is suffering acutely from a leadership vacuum. As America withdraws into insularity under President Donald Trump, the need for unity and authority is all too apparent. German Chancellor Angela Merkel is leading the way for Europe, but as the talks open in Hamburg, the focus is more on disunity than harmony.
The days when the US was happy to reach around the world since the founding of the UN, and Nato, seem far off. Reminders of the parlous nature of global politics can be seen in the tossing about of missiles by North Korea.
President Trump's twitterings, and the entirely muted responses of both Russia and China hardly reflect the level of danger. Mr Trump's climate change reversal has also cast a cloud over proceedings. It prompted Ms Merkel to say that the US could "no longer be relied upon". Little wonder few expect much to emerge from the Hamburg engagement.
