The US isn't a signatory to the ICC's founding statute and has previously said it has no jurisdiction in the states. Also, I would seriously doubt any NATO or EU country would comply with an arrest warrant for an Israeli leader given that Israel is a close ally to most large EU nations. That said, I wouldn't exactly book a safari to Kruger if I was Bibi.
I wouldn't be so sure about that. The Norwegian foreign minister has confirmed that Norway is obligated to carry out any arrest warrants issued by the ICC. France and several other countries have also issued statements.
"France supports the International Criminal Court, its independence and the fight against impunity in all situations", the foreign ministry said in a statement late on Monday.
Now, that's not exactly the same as saying "we'll arrest the prime minister of Israel if he comes here", but it's a far cry from the dismissive American statements. Of course, as yet there aren't actually any arrest warrants.
