Yes, the falling Ruble against the U.S. Dollar is a sign that people do not have a lot of faith in what Russia is going, because the falling Ruble is a sign that people do not expect good things for Russia's economy. People think that Russia will put its economic resources into Ukraine, rather than helping its own people.
It is very possible that the value of the Russian ruble would be dropping anyway based on the increased buying power of the US dollar. However, perhaps the rest of the world is finally realizing that doing business with the Russians at this time is not a net benefit. Russia's actions in Ukraine are harming the ruble.
Russia's actions are not benefiting them or their currency. This is because any time any other highly established countries take issue with a specific country's actions, their economy can take serious hits. Maybe their currency won't slide a lot right now, but there is potential for a lot of economic distress in Russia.
No country can take actions in the way Russia has lately without it affecting how they're perceived, and in turn how their currency does on the market. Of course Ukraine and the situation there is part of what's causing this - though no doubt Mr Putin would disagree. If they carry on this way they run a serious risk of long term damage to their country.
Did you know Putin planned the invasion/military mobilization before Russia hosts its Olympics? The amount of pressure and the sheer determination are results of single motivation---taking Ukraine. Putin can think ahead, and he did before the Olympics. Analogously, If Putin were stupid enough did not foresee the resistance he is facing now, why would he so determined to continue to advance in Ukraine. The answer only can be--- Taking Ukraine means good business. Where do the benefits come from? I don't know, but I am sure the Russian President knows it.
