And if an american, whom ICC have found guilty on crimes, visits a country which upholds ICC rulings they should be arrested, no?

Nobody talked about kidnapping people in the US or doing anything similar. In contrast, the US is in a habit on (among others)

1. kidnapping

2. bombing

3. otherwise assassinating

4. sanctioning

5. demanding extradition (the only actual "legal" part)

foreign citizens that they do not like. We can also say that no other, non american citizen has actually agreed to these practices either, nor to US authority to be the world serif. So these arguments more like read like monopoly of global violence/authority than "sovereignty".

And the ICC never tried to diminish their sovereignty. Juridsiction at the icc works the same way as it does with states.

If you commit a crime on the territory of a sovereign state, that state gets to punish you. If you are a citizen of a soverign state then that state gets to punish you.

That is how it works in countries, and that is how it works at the ICC . ICC is no different from any country. The crime has to happen on the territory of a member state or be comitted by a national of a member state (im ignoring the referral from UNSC part as that is obscure)

True, they could ignore the ICC, but they shouldn't go around sanctioning and punishing and threatening its judges.

Hence, if anyone commits a crime in another country, they fall under the jurisdiction of that country. So while the US doesn't have to recognize the ICC, listen to it, or follow its verdicts, other countries are free to do so.

But now the US is threatening the judges of the ICC, which is hypocritical to say the least. It's more of a mafia thing, really. Not surprising, given Trump's background.
