One of the most important post-9/11 efforts made to counter terrorism and the spread of weapons of mass destruction is President Bush's Proliferation Security Initiative (PSI).

Most Americans will be horrified that President Obama is compromising our deterrent to chemical and biological attacks on this country. Our allies will also be troubled by his aspiration to eliminate U.S. tactical nuclear weapons in Europe.

Since the presidency of Ronald Reagan, conservatives have succeeded by adhering to a platform that rests firmly on three legs: smaller government, faith and family, and a strong national defense. These three legs do not merely represent a political coalition; they are three necessary components of a strong and secure America.

Barack Obama has exhibited sympathy, if not for the terrorists, then certainly for the Islamic supremacists.

To his lasting credit, President Reagan never wavered. He recognized the strategic importance of staying the course, both in terms of denying Moscow the military hegemony it sought in Western Europe and of restoring the will, cohesiveness, and security of the NATO alliance, so badly frayed during the turbulent 1970s.

But I really believe it is in America's interest as well as that of the free world more generally to stop Iran from getting its hands on nuclear weapons. This regime has threatened to wipe Israel off the map and bring about a world without America, and either of those is a really bad prospect.

After all, from the Muslim Brotherhood's inception in Egypt in 1928, it has been a revolutionary organization committed to the imposition worldwide of a totalitarian, supremacist Islamic doctrine they call shariah.
