It's not a sign of strength. Anybody can make threats. Anyone can move an army. Anyone can show off a missile. That doesn't make you strong. It does not lead to security, or opportunity, or respect. Those things don't come through force. They have to be earned. And real strength is allowing an open and participatory democracy, where people can choose their own leaders and choose their own destiny. And real strength is allowing a vibrant society, where people can think and pray and speak their minds as they please, even if it's against their leaders — especially if it's against their leaders. Real strength is allowing free and open markets that have built growing, thriving middle classes and lifted millions of people out of poverty.
