Even if all of these issues are adequately addressed, there is a series of deeper challenges that the military, government and society must face. These are not restricted to Australia; every nation committing troops must ponder these issues.
The first challenge is intellectual. Australian troops would be deploying into the kind of mass, industrialised conflict which almost no living Australian has faced. But, they will also face the potential of massed use of drone and electronic warfare, an environment which is very different to other 21st century deployments by the Australian Defence Force. This will demand different organisational constructs, tactics and leadership approaches. But it will also harden and prepare our troops for 21st century conflict.
Second, there will be a profound physical challenge for the force. Nowhere will be safe. Russia has the capacity to conduct strike operations anywhere in Ukraine with drones and missiles, as well as with sabotage operations. This will demand good deception and force protection measures, that the force has integral electronic warfare, counter-drone and counter-intelligence capabilities, and that it operates under a coalition air defence umbrella. It also demands a different mindset from our soldiers.
Finally, the force which is deployed, and the society that supports it, must face up to some significant moral challenges. The government would need to accept more risk to the force than Australian governments did in Iraq and Afghanistan. Australian society must accept that casualties are possible and that the mission could involve mass casualty events, in the worst case. The government must be honest about such risks.
Finally, if such a force is deployed, it will be there to help stop the most clear-cut case of good versus evil, and of superpower moral delinquency, since the Second World War. Russia has systemically raped, tortured, murdered and looted its way through Ukraine. Our troops would be there to stop it. While the horrors inflicted on Ukrainian people will demand great resilience from peacekeepers, at the same time this gives soldiers purpose, which is the non-discretionary steel in any professional military force.
There is an alignment of Australia’s interests here, in protecting both its values and its prosperity through European security. Australia's soldiers are tough, well equipped, well trained and well led. They would be a net positive for any European peacekeeping force and would bring back important lessons on modern warfighting for the ADF.
Just one issue remains. In the midst of an ongoing and deepening Trumpian tragedy, does Australia have the will to do this while China is stepping up its military coercion against our nation?
