Yes, actions speak louder than words, but a US president speaking this way to an international body is actually quite significant. Here’s the relevant part of what he said:
And to make sure our societies reach their potential, we must allow our citizens to reach theirs. No country can afford the cancer of corruption. Together, we must harness the power of open societies and open economies. That is why we have partnered with countries from across the globe to launch a new partnership on Open Government that helps ensure accountability and empower their citizens. No country should deny people their rights because of who they love, which is why we must stand up for the rights of gays and lesbians everywhere. And no country can realize its potential if half its population cannot reach theirs. This week, the United States signed a new Declaration on Women’s Participation. Next year, we should each announce the steps we are taking to break down economic and political barriers that stand in the way of women and girls. That is what our commitment to human progress demands.
