The United States will ‘crush’ the UK economy if Britain helps arrest Benjamin Netanyahu, following an arrest warrant from the International Criminal Court (ICC).

Republican Senator Lindsey Graham told Prime Minister Keir Starmer that those who follow the ICC’s ruling could expect sharp economic consequences from the US.

‘Any nation or organization that aids or abets this outrage should expect to meet firm resistance from the United States, and I look forward to working with President Trump, his team, and my colleagues in Congress to come up with a powerful response,’ he said.

Unlike the United States and Israel, Britain is a member of the International Criminal Court and is obliged to act on arrest warrants it issues.

A spokesperson for No10 refused to comment on the specific case, but said this week the government would hypothetically fulfil its ‘legal obligations’.

The International Criminal Court issued an arrest warrant for the Israeli Prime Minister and former Defence Minister Yoav Gallant on Thursday, citing alleged war crimes in Gaza.

‘If you are going to help the ICC as a nation and force the arrest warrant against Bibi and Gallant…I will put sanctions on you as a nation,’ Senator Graham, himself a lawyer by training, told FOX News.

‘What they’re doing in Israel is trying to prevent a second Holocaust. So, to any ally, Canada, Britain, Germany, France, if you try to help the ICC, we’re gonna sanction you,’ the South Carolina senator added.
