Carl Bildt, former Prime Minister and Foreign Minister of Sweden, shares his perspective from Europe:

What was the CIA director doing in Moscow the other day?

I think it was an attempt to bring more stability to the long-term relationship between the US and Russia. That does not hide that there are serious concern when it comes to the Russian intention versus Ukraine. And you never know, you might have a crisis there, if not any day, then at any time. But of course, stability and the long-term relationship is good anyhow.
