JERUSALEM, Israel -- Many Americans and Israelis visiting each other's countries will have an easier time doing so.

Israeli Foreign Minister Avigdor Lieberman and U.S. Secretary of Homeland Security Janet Napolitano signed an agreement Sunday in Jerusalem, which will facilitate entry for Israelis and Americans making frequent visits to both countries.

The agreement includes cooperation on a broad range of security matters, including terrorism, cyber-terror, illegal immigration, drug smuggling and sex trafficking. 

The letter of intent will facilitate Israel's membership in the Global Entry program, which streamlines procedures at customs control for frequent travelers, such as people with family in both countries, diplomats and business travelers.

"There are 1.5 million travelers between the two countries every year," Napolitano said. "It is important that the wait be as short and comfortable as possible. Therefore we want the program to become active as soon as possible."
