I think your question should be directed to those who blame Soros, lol.

To sum up: Soros is basically lobbying on behalf of Ukraine, pushing for cash and guns, to oppose Putin in every way possible.
If genuine, and based on their meta data, they appear to be just that, these lettes show how Soros is trying to weasel around the Minsk agreements (for instance, how to train Ukrainian soldiers without having a visible NATO presence in Ukraine). The documents link up Nuland with Soros, and clears up who is truly pulling the strings of the US State Department.
Finally, while the documents don't mention what Soros has in store for Ukraine, one can use their imagination.
