Sao Paulo - For the last several decades, fundamental international issues of war and peace have been largely determined by a small group of countries, especially the permanent members of the United Nations Security Council, the US, Britain, France, Russia and China, with some input from the other so-called G7 industrial democracies: Germany, Italy, Canada, and Japan. The five permanent members of the UN Security Council each have a veto over UN Security Council resolutions; they are also the only countries recognized as nuclear-weapon states under the Nuclear Non-Proliferation Treaty.
We are now at a new moment in international relations, in which countries outside of the permanent members of the Security Council and their handpicked allies are insisting on having some meaningful input into these issues, and are starting to have some success in pressing their case for inclusion. Brazil has been a leader in these efforts.
The most striking example of this shift is the recent willingness of Brazil and Turkey to challenge the leadership of the United States on the question of responding to Iran's nuclear program.
