Mark Doran is right, this is textbook mafia behaviour - 'you have been warned' ffs, couldn't be much clearer. Rules-based order anyone?

Also nb the part where they invoke the American Service-Members' Protection Act. This has been dubbed the 'Hague Invasion Act':

'[...] as the act allows the president to order U.S. military action, such as an invasion of the Netherlands, where The Hague is located, to protect American officials and military personnel from prosecution or rescue them from custody' - https://en.wikipedia.org/wiki/American_Service-Members%27_Protection_Act

So in saying that they will view it as an attack on their sovereignty if the ICC issues arrest warrants for Israeli officials they are threatening a military operation in the Netherlands, or potentially anywhere else, to save them from prosecution.

The mask is well and truly off now. I like to think they're overplaying their hand. F*ing sick either way.

jeers,
