@luigirovatti The American Service-Members’ Protection Act has never been tested yet.
It’s an interesting hypothetical whether the US would directly violate another NATO state’s national sovereignty in order to “rescue” a credible war criminal.
Any initial arrest and detention could be in any number of participating signatory states. The transfer to the Hague is done later for the purpose of holding the actual trial. In theory, the US could intervene in whichever state carries out the arrest.
It’s pretty wild to me that the “Hague Invasion Act” also extends to any allied non-US actors.
My guess is that Netanyahu will just avoid going anywhere where he could theoretically be arrested. It’s pretty clear that many of the Rome Statute signatories would be reluctant to fulfil their treaty obligations anyway, and would rather avoid any embarrassment and pressure by simply not hosting Netanyahu in the first place.
