There’s a whip-smart 10-year-old girl in Gaza who speaks good English, displays a radiant smile and seemed to have a bright future. The daughter of an X-ray technician, she had been accepted to an international exchange program and was supposed to be leaving soon.

Instead, she’s lying in a hospital bed with a badly infected wound in her thigh from a bomb blast. A photo shows a football-size open wound, with a chunk of her femur missing.

“She was supposed to be in Japan,” said Dr. Samer Attar, an orthopedic surgeon who cared for the girl and told me about her. “Now she’s lying in bed deciding whether to have her leg removed.” I’ve known Dr. Attar for a decade, ever since he volunteered to work in secret hospitals in Aleppo, Syria, to save victims of Russian bombings. A professor at Northwestern University School of Medicine, he has worked in war zones and crisis areas around the world, including Ukraine and Iraq — and recently, at hospitals in Gaza, through the medical volunteer organizations Rahma Worldwide and IDEALS.

Dr. Attar said the girl needed an amputation at the hip to save her life. Her dad, struggling to come to terms with how his and his daughter’s lives have collapsed, is resisting for now.

Over the years, I’ve covered many bloody wars and written scathingly about how governments in Russia, Sudan and Syria recklessly bombed civilians. This time, it’s different: My government is on the side engaged in what President Biden has referred to as “indiscriminate bombing.” This is not the same as deliberately targeting civilians, as those other countries did — but this time, as a taxpayer, I’m helping to pay for the bombs.

Gaza is also different from Syria and Ukraine, of course, in that Israel did not start this war. Instead, Israel was brutally attacked by Hamas in a rampage of murder, torture and rape. Any government would have struck back, and Hamas maximized the suffering of civilians by using them as human shields.
