"Mr. Secretary, if the situation remains unchanged until the end of Ramadan this camp will become empty," said one of the women from Daara, who asked not to be named for fear of reprisal against her or her family. "We will return to Syria and we will fight with knives."
"You as the U.S. government look to Israel with respect," she said. "Cannot you do the same with the children of Syria?"
"The international community can decide to keep its eyes closed as long as it wants. We will return to Syria and we will remember everything," said one of the male refugees, who also asked not to be named for fear of reprisal.
In Washington, the chairman of the military's Joint Chiefs of Staff told a Senate committee the Obama administration is deliberating whether to use military power in Syria.
Army Gen. Martin Dempsey, appearing at his confirmation hearing for another term, said he has provided President Barack Obama with options for the use of force in Syria.
Dempsey used the term "kinetic strikes," and added that the "issue is under deliberation inside of our agencies of government." But he did not provide additional details, saying the decision on whether to engage militarily is one for U.S. elected officials to make.
Kerry had been warned of a possible hostile reception at the camp, where refugees frustrated at their living conditions and deteriorating conditions in their homeland have in the past attacked U.N. staff and other aid workers, but chose to go anyway to see the situation first-hand, according to U.S. officials.
"The stories that I've just heard and the people that I've just met put a real face on the level of the humanitarian crisis," Kerry told reporters after meeting the refugees. "Coming here today puts a very real, human face and a searing, unforgettable passion and urgency to our needs to try to address it on an international scope."
Kerry spent his time in Zaatari at the camp's administrative base, which is separated by a fence from the tens of thousands of prefabricated aluminum trailers in which the refugees live. He did not tour the dusty living quarters.
In his conversation with the refugees, Kerry attempted without apparent success to explain the U.S. position.
"A lot of different options are under consideration," he said after being repeatedly pressed for a no-fly zone. "I wish it was very simple. As you know, we've been fighting two wars for 12 years. We are trying to help in various ways, including helping Syrian opposition fighters have weapons. We are doing new things. There is consideration of buffer zones and other things but it is not as simple as it sounds."
"You are not abandoned," he insisted. "We are very aware of how terrible conditions are inside Syria. I came here today because we are concerned. I promise you I will take your voices and concerns back with me to Washington as we continue to work with our friends in ways that can be helpful."
After the meeting, Kerry told reporters he understood the refugees' concerns.
"I think they are frustrated and angry at the world for not stepping up," he said. "If I was in their shoes I would be looking for help wherever I could find it. I share their passion and frustration for the plight that they face on a day-to-day basis."
The Zaatari camp was set up last July and was at one point in April receiving an average of 1,500 new arrivals each day. The current population is down from a high of nearly 130,000 because some people are leaving some to go back to join the fight, some to tend to properties in areas that are relatively safe and some into Jordan proper if they can prove they have relatives already there, according to the U.N. High Commissioner for Refugees.
But people are still arriving, although in smaller numbers than before; most Syrians who lived closest to the border are already in Jordan and the new arrivals are coming from farther away, camp manager Killian Kleinschmidt said, One hundred arrivals Wednesday night had spent 17 days on the road coming from the Homs area, about 200 miles away, he said.
Despite the slight reduction in the camp's population, the stories from incoming refugees suggest the situation inside Syria is getting worse, Kleinschmidt said.
"The conflict has reached a level of brutality that is unbelievable," he said, adding that every family in the camp can tell stories of rape, torture, arrest and disappearances. Children draw "horrible pictures of destruction," he said.
Kerry is in Jordan on his sixth trip to the Middle East in as many months as secretary of state and flew by Jordanian military helicopter to the Zaatari camp northeast of Amman, about 12 kilometers from the Syrian border, accompanied by Jordanian Foreign Minister Nasser Judeh.
