Video Feature: Larry Greenfield, Executive Director of the Reagan Legacy Foundation, spoke with Israel National Radio's Tovia Singer at this year's Jerusalem Conference on the missile threat against Israel.

"There's a race against the clock," Greenfield said. "Not enough has been done to meet the missile threat by creating a better missile defense system. It's missiles against missile defense."

Greenfield says that Barack Obama originally comes from the school that says that missile defense scares the world. However, he has become sobered by his first year in office, Greenfield says, and is now more ready to move ahead on missile defense systems.
