I summarized to include main points of article got required excerpt, however check full article at link
Unrelated but about Ukraine, this lady in Russia is being tried for treason in Russia: http://www.rferl.org/content/russia-ukraine-treason-mother/26828233.html
Here is the gist of what she is accused of:
“Davydova’s husband, Anatoly Gorlov, has said that his wife phoned the Ukrainian Embassy in Moscow in April and said a military base near their home had emptied out, suggesting the soldiers may have been deployed to Ukraine.”
“The case has sparked heated debate in Russia, where some critics say the charges against Davydova amount to a tacit admission that Russian military personnel are operating in eastern Ukraine.”
Currently the biggest opponent for helping Ukraine seems to be the White House.
This article says Susan Rice of the White House has been stopping sending weapons to Ukraine clashing with General P. M. Breedlove over it. http://www.nytimes.com/2015/02/02/world/us-taking-a-fresh-look-at-arming-kiev-forces.html?_r=0

.. but the relevant part there is that the Congress is willing to help Ukraine, but the White House opposes.
