This week's suicide bombing in Bulgaria, the latest in a string of attacks around the world, has made it clear that being an Israeli traveler can be risky business. But Israel's famously globe-trotting people show no signs of curbing their wanderlust, even if the globe seems to offer a shrinking number of safe destinations for them.

Living in a tiny country, and long accustomed to dealing with terrorism, Israelis have always been quick to return to their routines following tragedies and disaster. The Bulgaria bombing appeared to be no exception. At Israel's Ben-Gurion International Airport on Thursday, travelers were jittery, but it was largely business as usual: Long lines of people were checking in for flights at the height of the summer vacation season.

"We are a people with a history of thousands of years, but a memory of only one day," said Yossi Fatael, managing director of the Israeli travel agents' association.
