You can't really bring non binding, non serious agreements that were never put in writing or ratified and that all parties declared no longer relevant back from the dead and feign moral outrage. That's ridiculous.
What does "legally binding" do good at all? There are no other laws other than the rule of the strength.
U.S. was strong for a long time. It did whatever it liked.
Now Russia restored some of its strength to the point it can show others that sometimes you have to listen to when a bear warns you (quite calmly and nicely first).
Many people (even Americans) claim U.S. is not a democracy. Every country has corruption to some degree. The only backing and staying power there is - is the force a country has and its willingness to use it to defend something.
