US President Barack Obama said in Military Academy commencement ceremony at West Point, New York “The United States will use military force, unilaterally if necessary, when our core interests demand it – when our people are threatened; when our livelihood is at stake; or when the security of our allies is in danger.”
“In these circumstances, we still need to ask tough questions about whether our action is proportional, effective and just. International opinion matters. But America should never ask permission to protect our people, our homeland, or our way of life.”
“On the other hand, when issues of global concern that do not pose a direct threat to the United States are at stake – when crises arise that stir our conscience or push the world in a more dangerous direction – then the threshold for military action must be higher. In such circumstances, we should not go it alone. Instead, we must mobilize allies and partners to take collective action. We must broaden our tools to include diplomacy and development; sanctions and isolation; appeals to international law and – if just, necessary, and effective – multilateral military action. We must do so because collective action in these circumstances is more likely to succeed, more likely to be sustained, and less likely to lead to costly mistakes.”
“In the Asia Pacific, we are supporting Southeast Asian nations as they negotiate a code of conduct with China on the South China Sea, and are working to resolve territorial and maritime disputes through international law,” US President said.
