The International Rules-Based Order: Nostalgia or Blueprint for Global Peace?

Following the US’ recent bombing of Iranian nuclear facilities, Australia’s acting shadow foreign affairs spokesman said the "world is governed by might and not right, and anyone who talks about this rules-based global order is really being nostalgic”.

Recent conflicts in Sudan, Ukraine, Gaza, Lebanon and Iran – along with an unprecedented 123 million refugees seeking protection and global trade instability – are challenging the post-Second World War international regime that prohibits the acquisition of territory by force, promotes free trade and protects human rights.

Emeritus Professor Gillian Triggs AC will examine whether international law remains an effective part of the' rules-based order’ when, today, some political leaders explicitly deny fundamental norms, reject multilateral treaty obligations, and resort to unilateral policies. In short, is the United Nations Charter and the laws and institutions built upon it still fit for purpose?

If 20th century international law no longer inspires a commitment to peace, security and human rights, we need to ask what reforms are possible in a world riven by conflict, ideological divisions, rising poverty and inequality.
