In the next paragraph, Carter offered a now unsettling warning about what form that violent resistance might take. He explained that Palestinian and Lebanese militants knew the value of a captured Israeli soldier or civilian. As a result, absent an Israeli commitment to peace, militants would have an incentive to obtain hostages. Israel would then respond with overwhelming and disproportionate force. But it likely wouldn’t be enough to destroy the hostage takers, Carter warned. After the bombs stopped falling, they would emerge more popular than ever.
Looks like he definitely knew what he was talking about.
