> You as an individual are not sovereign, and when you come to the land over which the US is sovereign, you are subject to US law.

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".
