Yet the importance of defeating Russia’s aggression in Ukraine remains every bit as great as it has ever been. The consequences of ceding a victory to Putin – both in emboldening his aggressive intentions towards neighbouring European states,and in sending a message to autocrats elsewhere – are exactly the same now as they were two years ago.

Australia has begun to succumb to the ennui that has afflicted so much of the democratic world. As shadow foreign affairs minister Simon Birmingham wrote recently:“We are not doing enough to defeat Putin. By we,I mean Australia,but also some of our fellow liberal democracies,with signs of fatigue,disinterest or even worse.”

That is evident from Australia’s declining share of international assistance to Ukraine. Our initial response to the invasion,led first by Scott Morrison and then by the newly elected Anthony Albanese,was strong. In the months after the invasion,Australia was the largest donor of assistance to Ukraine of any non-NATO nation. But no longer.

Germany’s Kiel Institute publishes a“Ukraine Support Tracker”. The latest data reveals that,in aggregate military,humanitarian and financial assistance,Australia has fallen well behind the other large Indo-Pacific economies,Japan and South Korea,in the assistance we provide to Ukraine. Of the donor nations in our region,only New Zealand contributes less.

Our failure is evident in other ways. One is the decision last year to refuse Ukraine’s request for our decommissioned Taipan helicopters. Even if dogged by safety issues,they had been an operational part of the army for years. We could have given them;instead we junked them. It is also evident in the refusal of requests to supply Hawkei vehicles,for reasons that sound very much like Defence bureaucracy doublespeak. Ukraine’s immediate need for these is obviously more acute than Australia’s. There is also our parsimony in the supply of Bushmaster PMVs:120 from a fleet of more than 1000.

It is understandable that Defence chiefs want to keep their inventories intact. But in the end,war machines are made for fighting;the Russia-Ukraine War is the world’s most dangerous conflict since World War II;and as leaders from both sides of politics acknowledge,it directly affects our national interests.

In our support for Ukraine,Australia has become rather like a well-meaning,well-to-do citizen who regularly makes generous contributions to charity,but not so substantial that they really notice it. More than a gesture,but well short of what we could and should be doing.

This Thursday – Anzac Day – the Kiel Institute will publish its latest update on support for Ukraine. As Australians reflect on war and sacrifice,it is appropriate,too,to reflect on the price of failing to stand up to aggressors. Which is not done by words alone.
