I support development and deployment of a limited national missile defense. Few if any of our duties surpass our obligation to provide for the common defense of our nation.

Every day Saddam remains in power with chemical weapons, biological weapons, and the development of nuclear weapons is a day of danger for the United States.

I believe that our national security lies not just in protecting our borders, but in bridging divides.

I also urge the Obama administration - both on its own and in cooperation with other responsible governments around the world - to use all legal means necessary to shut down WikiLeaks before it can do more damage by releasing additional cables. WikiLeaks' activities represent a shared threat to collective international security.

The essential facts are known. We know of the weapons in Saddam's possession: chemical, biological, and nuclear in time. We know of his unequaled willingness to use them. We know his history. His invasions of his neighbors. His dreams of achieving hegemonic control over the Arab world. His record of anti-American rage. His willingness to terrorize, to slaughter, to suppress his own people and others. We need not stretch to imagine nightmare scenarios in which Saddam makes common cause with the terrorists who want to kill us Americans and destroy our way of life.

It (Lewinskygate) has...compromised his moral authority

Community means engaging constructively with like-minded nations to build strong, sustaining institutions and alliances - and bringing emerging powers into this community so future conflict becomes less likely.
