Israel’s closest allies on Monday criticized the decision of International Criminal Court prosecutor Karim Khan to seek arrest warrants for Prime Minister Benjamin Netanyahu and Defense Minister Yoav Gallant alongside three leaders of the Hamas terrorist organization.

US President Joe Biden called the decision “outrageous.”

“Let me be clear: whatever this prosecutor might imply, there is no equivalence — none — between Israel and Hamas,” Biden said in a statement. “We will always stand with Israel against threats to its security.”

In his own statement, US Secretary of State Antony Blinken said the Biden administration “fundamentally rejects” Khan’s decision.

“We reject the prosecutor’s equivalence of Israel with Hamas. It is shameful. Hamas is a brutal terrorist organization that carried out the worst massacre of Jews since the Holocaust and is still holding dozens of innocent people hostage, including Americans,” Blinken said.

The secretary of state reiterated the long-held US stance that the ICC has no jurisdiction over the Israeli-Palestinian conflict, in no small part due to the fact that Israel — and the US — are not members of the court.

“The ICC was established by its state parties as a court of limited jurisdiction. Those limits are rooted in principles of complementarity, which do not appear to have been applied here amid the prosecutor’s rush to seek these arrest warrants rather than allowing the Israeli legal system a full and timely opportunity to proceed,” Blinken said.

“In other situations, the prosecutor deferred to national investigations and worked with states to allow them time to investigate. The prosecutor did not afford the same opportunity to Israel, which has ongoing investigations into allegations against its personnel,” he continued.

“There are also deeply troubling process questions,” Blinken said on Monday. “Despite not being a member of the court, Israel was prepared to cooperate with the prosecutor. In fact, the prosecutor himself was scheduled to visit Israel as early as next week to discuss the investigation and hear from the Israeli government. The prosecutor’s staff was supposed to land in Israel today to coordinate the visit. Israel was informed that they did not board their flight around the same time that the prosecutor went on cable television to announce the charges.

“These and other circumstances call into question the legitimacy and credibility of this investigation,” he added. “Fundamentally, this decision does nothing to help and could jeopardize, ongoing efforts to reach a ceasefire agreement that would get hostages out and surge humanitarian assistance in, which are the goals the United States continues to pursue relentlessly.”

On Monday afternoon, a spokesperson for UK Prime Minister Rishi Sunak said that the decision by the ICC prosecutor is unhelpful.

“This action is not helpful in relation to reaching a pause in the fighting, getting hostages out or getting humanitarian aid in,” the spokesperson said.

The spokesperson said the ICC did not have the jurisdiction to request the arrest warrants: “The UK, as with other countries, does not yet recognize Palestine as a state and Israel is not a state party to the Rome Statute,” which outlines the ICC’s areas of jurisdiction, the spokesperson said.

Asked if the police would arrest Netanyahu if he came to Britain, the spokesperson said he would not comment on what he called “hypotheticals.”

British deputy foreign minister Andrew Mitchell later told parliament that the ICC’s decision would not have an immediate impact on the government’s approval of licenses so companies can sell weapons to Israel.

“The fact that the prosecutor has applied for arrest warrants to be issued does not directly impact, for example, on UK licensing decisions, but we will continue to monitor developments,” Mitchell said.

Czech Prime Minister Petr Fiala called the ICC prosecutor’s decision “appalling and completely unacceptable.”

“We must not forget that it was Hamas that attacked Israel in October and killed, injured and kidnapped thousands of innocent people,” he wrote on X. “It was this completely unprovoked terrorist attack that led to the current war in Gaza and the suffering of civilians in Gaza, Israel and Lebanon.”

Austrian Chancellor Karl Nehammer said in a statement that Vienna supports the independence of the ICC, but “the fact, however, that the leader of the terrorist organization Hamas, whose declared goal is the extinction of the State of Israel, is being mentioned at the same time as the democratically elected representatives of that very state is non-comprehensible.”

Several US Republican lawmakers also spoke out in support of Israel and against the ICC prosecutor’s decision.

Sen. Jim Risch, the senior Republican on the US Senate Foreign Relations Committee, said in a statement that “there is no cause for why the court should be investigating Israel as it is not a party to the Rome Statute and Israel has a fully functional judiciary.”

Republican Sen. Lindsey Graham wrote on X that the “outrageous decision is truly a slap in the face to the independent judiciary in Israel, which is renowned for their independence.”

Graham vowed to “feverishly work with colleagues on both sides of the aisle in both chambers to levy damning sanctions against the ICC.”

The senator said that he had engaged with the ICC recently and was told that there would be additional meetings and consultations that would take months, but instead the ICC prosecutor announced the request for warrants on Monday: “I feel that I was lied to and that my colleagues were lied to. Prosecutor Khan is drunk with self-importance and has done a lot of damage to the peace process and to the ability to find a way forward.”

Meanwhile, Belgian Foreign Minister Hadja Lahbib posted on X that Brussels supports the work of the ICC.

“Crimes committed in Gaza must be prosecuted at the highest level, regardless of the perpetrators,” she wrote. “The fight against impunity wherever crimes occur is a priority for Belgium.”

Lahbib added that Khan’s request for arrest warrants against both Israeli and Hamas leaders “is an important step in the investigation of the situation in Palestine.”
