Not yet. I doubt Russia is going to make such claims until it has military capability that is greater than the one U.S has. Not even the Soviet Union did regard Alaska as an issue or the fact it used to belong to Russia (pre-Soviet Union). Russia today under Putin is dangerous country and its media is full of lies and deceptions.
As for list of Russia land grabs. It seems we have our next target. That is Kazakhstan.
While Daily Mail is not the most reliable source, they just might have a point on Russia wanting to take over Belarus too. Even if they are now "allies", or so the dictator of Belarus believes at the moment.
Putin is not out to build new Soviet Union. He is out to expand Russia and that is a totally different matter. He has already had some success doing to with his less economic able neighbour countries.
