Who owns .com domain
Governing authority for the TLDs
The Internet Corporation for Assigned Names and Numbers (ICANN) - https://www.icann.org/
United States Department of Commerce
VeriSign, Inc. (Verisign)
Verisign's operation of the .COM TLD is governed by two separate agreements: the .COM RA, and the Cooperative Agreement between Verisign and the U.S. Department of Commerce. In 2016, Verisign and ICANN formally agreed that if and when the Department of Commerce and Verisign made changes to the Cooperative Agreement, ICANN and Verisign would negotiate in good faith to ensure those changes were reflected in the .COM RA.

Google Domains
PROVISIONS SPECIFIC TO .COM, .CC, .NAME, .NET AND .TV REGISTRATIONS. Verisign, the Registry Operator for .COM, .CC, .NAME, .NET and .TV, reserves the right to deny, cancel or transfer any registration or transaction, or place any domain name(s) on registry lock, hold, or similar status, as it deems necessary, in its unlimited and sole discretion: (a) to comply with specifications adopted by any industry group generally recognized as authoritative with respect to the Internet (e.g., RFCs); (b) to correct mistakes made by Verisign or any registrar in connection with a domain name registration; or (c) for the non-payment of fees to Verisign. If Registrant is registering a .NAME domain, Registrant certifies that it complies with the .NAME Eligibility Requirements.
Verisign has operated in the grey areas of its contract with ICANN. Verisign is leveraging some subtle law suit tactics to gain monopoly over the registry business with ICANN.
One important thing to note is for the last 20+ years Verisign managed to keep the stability. But, this should not be taken for granted. A new competitive bidding process with better negotiating terms are required.

As per the ICANN blog post,
U.S. sanctions are set not through an agreement between the international community, but through the unilateral decision of the U.S. to assert sanctions on certain countries, mainly due to mutual conflicts that do not affect the rest of the world. The U.S. has some of the harshest and limiting sanctions against some countries, due to its historical conflicts. If we consider the Internet as a global resource, then actions that hamper access to that resource should not be imposed by one country.
