Obama has a lot of stuff he has to deal with on a daily basis - listening to the audio, it would make sense that she is calling the shots on a daily basis. you can hear her saying that she is going to arrange biden to give an "attaboy" which is basically "i need a guy in a leadership role to appear to bless this" not that biden is actually making any substantive decisions.

Her brother-in-law came up with Bush's "surge" strategy in 2007, her husband was a foreign policy advisor to mccain in 2008. i would guess that's not the full extent of their republican advisory work but that's all i found in a minute or two on wikipedia.
TOTALLY irrelevant here. Logical fallacy violated. Non sequitor.
EDIT: Seriously, you think Victoria Nuland, by herself, is pulling the strings of the American foreign policy?
Here's the state department org chart.

The assistant secretary position she holds is responsible for that area, and two links below the secretary of state.
How is Russia invading when it already has a massive military base there, in the Crimea, which was Russian until 1954?
The law matters, yes. And so does how Russia feels about Crimea. Both need to be considered.
However, I will be surprised if Russia doesn't retain control of Crimea.
The same way the US would have been invading if it invaded the Phillipines in 1991, where it had a massive military base and which had been American up until 1946. Neither "this was our territory ~50 years ago" nor "we have a massive military base in this territory" gives a country permission to invade and occupy a territory.
