Every great power needs an organising principle of foreign policy; great powers rise and fall on the tide of history and no power remains great forever; no great power retreats forever; there’s no way to reliably judge whether a great power has begun its descent into permanent decline or is merely in temporary retreat; and geopolitical fault lines during periods of power transition are fraught with grave risks of war rooted in miscalculations of relative power.

Proving that history does irony, banks that once feared masked robbers now fear mask-free customers. But does history also do mockery? The 1984 Nobel Peace laureate Archbishop Desmond Tutu passed away on Boxing Day in Cape Town. Almost a decade ago, Tutu refused to share the stage with former British prime minister Tony Blair in Johannesburg, saying he should be in the dock in The Hague answering for war crimes.

After constant Cold War rhetoric and sabre-rattling, the presidents of the USA and Russia talk to each other about the Ukraine conflict and more generally about the security architecture in Europe. The EU is directly affected but is left out and wonders.

The new German coalition government will not rock the foundations of German foreign and security policy. It wants to remain a reliable partner in the EU and NATO. But it sends an important signal for disarmament and arms control efforts. The 177-page coalition agreement contains the following passage on the TPNW: "In light of the results of the NPT Review Conference and in close consultation with our allies, we will constructively accompany the intention of the treaty as observers (not as members) at the Conference of the Parties to the Treaty on the Prohibition of Nuclear Weapons."

Prime Minister Scott Morrison is embroiled in a tussle with both French President Emmanuel Macron and US President Joe Biden which, given the power asymmetries, risks leaving Australia exposed and vulnerable in a major-power league above its paygrade.

In recent months, we have often heard that the return of the Cold War is imminent, this time with China. How great is this danger? Some developments point at a dangerous confrontation; others are completely different from the times of the Cold War with the Soviet Union and its allies.
