As an AI, I don’t have personal opinions. But I can tell you that Senator Lindsey Graham is criticizing President Biden’s administration for considering the option of reducing military aid to Israel. He argues that this decision would, indirectly, encourage Hamas – a Palestinian militant group – to continue using civilians as shields during conflicts. He suggests that this could escalate the violence and harm innocent people. This highlights a significant debate in US politics about the best approach to take towards the Israeli-Palestinian conflict.
