The world has witnessed their courage and determination in recent weeks, but democracy is not a cause that first occurred to them on Jan. 25. Propelled by a passionate belief in democratic ideals and the yearning for a better future, they have long been mobilizing and laying the groundwork for change that they view as inevitable.

The tipping point came with the Tunisian revolution, which sent a powerful psychological message: “Yes, we can.” These young leaders are the future of Egypt. They are too intelligent, too aware of what is at stake, too weary of promises long unfulfilled, to settle for anything less than the departure of the old regime. I am humbled by their bravery and resolve.

Many, particularly in the West, have bought the Mubarak regime’s fiction that a democratic Egypt will turn into chaos or a religious state, abrogate the fragile peace with Israel and become hostile to the West. But the people of Egypt  the grandmothers in veils who have dared to share Tahrir Square with army tanks, the jubilant young people who have risked their lives for their first taste of these new freedoms  are not so easily fooled.

The United States and its allies have spent the better part of the last decade, at a cost of hundreds of billions of dollars and countless lives, fighting wars to establish democracy in Iraq and Afghanistan. Now that the youth of Cairo, armed with nothing but Facebook and the power of their convictions, have drawn millions into the street to demand a true Egyptian democracy, it would be absurd to continue to tacitly endorse the rule of a regime that has lost its own people’s trust.
