In a world where global politics is no longer a zero-sum game, it is - or should be - counterintuitive to pursue one's interests without considering the interests of others.

International politics is no longer a zero-sum game but a multi-dimensional arena where cooperation and competition often occur simultaneously. Gone is the age of blood feuds. World leaders are expected to lead in turning threats into opportunities.

I think that the president of Iran has the authority wherever which - where - wherever the national interests of the country are involved and, when it is necessary and expedient and required to speak and talk with others in order to promote the rights of its nation, that the president can take that initiative.

As leaders, we need to rise above petty politics and lead, rather than follow, the various interests and pressure groups in our respective countries.

Global challenges require collective responses.

I've said before that I am not a historian and that when it comes to speaking of the dimensions of the Holocaust, it is the historians that should reflect on it.
