Critics argue that Iran and North Korea maintain nuclear ambitions, the security situation in Afghanistan continues to be perilous and Israeli-Palestinian relations have yet to improve.
But Mrs Clinton said that US had “begun to see the dividends of our strategy.”
“We are advancing America’s interests and making progress on some of our most pressing challenges,” she said.
Mrs Clinton also noted that the world continues to look to the US for leadership in times of crisis, calling that both a responsibility and an unparalleled opportunity to seize upon.
“The world is counting on us. When old adversaries need an honest broker or fundamental freedoms need a champion, people turn to us,” she said.
But she stressed the importance of international partnerships.
“This is no argument for America to go it alone,” Mrs Clinton said.
“The world looks to us because America has the reach and resolve to mobilize the shared effort needed to solve problems on a global scale – in defence of our own interests, but also as a force for progress. In this we have no rival.”
