During the recent Hamas war in Gaza, the Biden administration's plan to mobilize international alliances to pressure Hamas and end the war was met with reluctance and dismissal from European countries and other allies. European officials expressed concerns about being dragged into Netanyahu's war and refused to cooperate. A Biden aide expressed frustration over the missed opportunity and the extended duration of the conflict. The aide was particularly angered by the International Criminal Court's decision to issue arrest warrants for Prime Minister Benjamin Netanyahu and former defense minister Yoav Gallant, and criticized the European Union's support for the court's ruling. The Biden administration hopes that the 100 hostages held in Gaza will be released before President-elect Donald Trump takes office.
