The two Americans killed in fighting in the Gaza Strip followed in the footsteps of scores of Jews from around the world who have volunteered to fight for Israel.
Israel calls them the lone soldiers: They are men and women in the prime of their lives who have left their parents and often comfortable lives behind in places like Sydney, London, Los Angeles and elsewhere to join the Israel Defense Forces, marching in the desert and taking up arms to defend the Jewish state.
There were about 5,500 lone soldiers serving in the military in 2012, according to the Israel Defense Forces. Groups for families of lone soldiers have recently started in Los Angeles and other cities, providing a support network as the fighting intensifies.
For Jews who left Israel before the age of 15 or who never lived there, their service is voluntary. For many, it is a calling, a way to get back to their roots and unite the world's Jewish population. Some have dual citizenship. Others speak little to no Hebrew and have only recently been to Israel.
Max Steinberg, 24, who grew up in Southern California's San Fernando Valley, joined six months after he visited Israel for the first time on a Birthright Israel trip with his younger brother and sister in June 2012, said Jake Steinberg, who spoke to The Associated Press hours after learning his brother, a sharpshooter in the Golani Brigade, was among 13 Israeli soldiers and scores of Palestinians over the weekend who died during the first major ground battle in two weeks of fighting between Israel and Hamas. The Jewish Journal was first to report Steinberg's death.
"He got there and felt a connection to Israel, saw that as a place he could live and be successful, and he went for it," Jake Steinberg said.
Nissim Sean Carmeli, 21, the second American killed, was from South Padre Island, Texas, and he felt that same strong connection to the country he had only moved to four years ago.
"Lone soldiers are a kind of star in Israel," according to the Jewish Journal in a report. "For Israeli kids, army service is a rite of passage. But because it is a choice for the young members of the Diaspora who re-direct their own life paths to protect Israel, those enlistees are given a hero's welcome — and a lifetime of Shabbat dinner invitations from their fellow soldiers, who become their surrogate families."
Thousands of people attended Carmeli's funeral in the northern Israeli port town of Haifa after a Facebook status called for Israelis to come in droves so that the lone soldier would be not be alone at this final resting place. Tearful mourners rested their heads on his coffin, which was draped in an Israeli flag. Before it was lowered into the grave, piles of flowers were set upon the coffin, as mourners cried beside it.
Mike Fishbein, who grew up in Los Angeles, said he felt like he was missing a connection to his Jewish identity in California. He spent a year volunteering and studying in Israel, but that experience only deepened his desire to do more.
"I believe in that country. I believe in the Jewish people and the country's reason to exist, so I thought I can't just go back home to Los Angeles," said Fishbein, who served about two years with the Israel Defense Forces starting in 2009.
After Fishbein enlisted, he spent 30 days learning Hebrew along with more than two dozen others from Panama, South Africa, Australia and other nations. He then went through basic training, which included a 40-mile nighttime march through the desert. He lived for almost four months inside a worn tent from the Vietnam War era.
Israeli troops wondered why he would leave the palm trees and beaches they had seen in movies.
"They didn't understand why a kid from Hollywood was there," he said. "But after you stuck around, they would respect you and understand (that) we're here together to try and protect the same thing."
When Fishbein heard of the two Americans killed, it touched him deeply, he said. He has struggled to post on his Facebook page his emotions or even give an explanation to his friends in California as to why he felt the need to serve. He never wanted to join the U.S. armed forces, Fishbein said.
For the 25-year-old commercial production assistant, serving in the Israel Defense Forces was the culmination of milestones in his life, he said. In ninth grade, he accompanied his father with a documentary crew filming the unearthing of Jewish artefacts in a once largely Jewish town in Poland that was destroyed in the Holocaust.
"That was a surreal experience for a ninth-grade kid to go through, but it set me up to go to Israel and serve," he said. "Every lone soldier has had something similar."
Josh Reznick, 24, who works for a real estate investment firm in Baltimore, briefly considered joining the U.S. military, but after living on a kibbutz for a year, he realized his calling. He served in the same unit as the two Americans killed during the weekend. He didn't know either of them, but he did know one of the fallen Israeli troops.
Reznick believes the Steinberg and Carmeli will be "shining examples" for other lone soldiers. He was inspired by Michael Levin, a lone soldier from Pennsylvania killed fighting for Israel in 2006. He visited his grave site in Israel, where his tombstone is covered in Phillies baseball hats and Eagles jerseys.
"It's very nice living in America and everything is fine. But I'm sure people right before WWII felt the same way about living in Germany," he said. "If only there had been a place to run to for the Jews. That's why it's important to keep Israel, a Jewish nation, alive."
Isaac Cohen, 18, of Silver Spring, Maryland, starts this month at an Israeli military prep school before joining the army next year. He isn't deterred by the recent violence.
"They teach you how to survive in Israel," said Cohen, who lived there for six years. "You kind of have to survive there. I feel a lot stronger when I'm there."
