HTTPS is becoming increasingly important for every website out there on the internet and even on intranet sites. As HTTPS prevents eavesdropping and MiTM attacks. All major browsers discourage visiting HTTP-only websites and there are multiple initiatives to issue TLS/SSL certificates needed for HTTPS to as many websites as possible..... except to websites based in US-sanctioned countries.
The prime example of excluded from the secure internet due to US sanctions is the DPRK. While the China-based DPRK website Uriminzokkiri has a valid TLS/SSL certificate, all DPRK-based websites such as Naenara, KCNA, Voice of Korea and Rodong Sinmun do not have access to any kind of TLS/SSL certificate.
What do we do? Try to take action via our US-based comrades? Try to start our own CA?
There's not much you can do except advocate for the use of DANE in browsers: this lets site operators pin their certificates in DNS. It is tricky because it is linked to the operation of DNSSEC at the moment. Have a read:
