People-to-People Diplomacy. To Russia w/ Love

01.10.18 - The U.S. State Dept. issued a warning titled "Russia – Level 3: Reconsider travel" that seems to generalize the same risk level over all of Russia; Moscow included (the city where most travelers go). Is traveling to Moscow as risky as to Mt. Elbrus?

The 10+ pager (at times seems to have been written before 2017*) doesn’t have a single good word about Moscow. E.g. 'The Moscow Metro is generally not accessible to persons with disabilities'. Disabled tourists hardly visit Moscow Metro's 200+ stations but the best ones of the Moscow Metro Tour ARE accessible. Is the warning a part of the sanctions plan against 'Moscow', its people?
