Does not work that way. How do you think Iran and North Korea are connected to Internet in the first place? For NTT and US, such a situation would be a PR disaster. It would be very difficult for them to explain to the public, why they are applying foreign laws to Japanese citizens. Even US knows that, and they would never push for such draconian thing.
> Does not work that way. How do you think Iran and North Korea are connected to Internet in the first place? It literally works that way. North Korea is connected through China Unicom, and China doesn't recognize the North Korean sanctions. Iran's internet access isn't part of the current sanctions. >OFAC or the State Department may also impose so-called “secondary sanctions” on non-US companies, even with no US nex…
And this is the key.
In order to the hypothetical NTT situation to be affected by US sanctions, Japan would have to recognize them. It would be up to the Japanese parliament to adopt them. US cannot force NTT unilaterally to kick out someone, NTT in Japan must be in line with Japanese law.
Most countries in the world do not adopt US sanctions as their own. The sanction are being enforced worldwide via contract law (i.e. the exporting company has a contract with the US vendor that it won't sell to specified parties); not by US forcing its jurisdiction on other countries.
That would result in pretty nasty questioning about democracy.
