I disagree. Putin cannot "force his will on Europe by coercion." MEPS (e.g. European Parliament) won't even let Putin's Russia become a "strategic partner" of Europe formally despite their 1994 agreement stating Putin's Russia is "out of step" with the WTO, European "values" (e.g. loose anuses and submitting to external "bodies" like the UN/WTO lolol), etc...
Nearly all of Putin's close friends in Europe have lost power in Putin's current presidency and Europe is not as concerned as it once was with the wider world (including Russia). Berlusconi and his political machine have been replaced and he is facing prison, Mario Monti isn't interested anymore, France's Chirac retired from politics, and Sarkozy was voted out of office the day before Putin was inaugurated. All Putin has left is Merkel and those ties are weak. European leaders are focused on Europe now. Russia is in the back seat politically speaking.
Sure Russia influences Europe's natural gas market but Europe has massive gas reserves waiting to be tapped. If Russia cuts them off, Europe will finally overcome their issues/objections and tap it (e.g. lack of mineral rights on private land, bureaucratic obstacles, green lobby, and pipelines). The economic benefits would be huge and probably end Europe's recession.
Finally, Putin doesn't have as much control as you think he does. Like many a Russian leader throughout history, he gives orders and in the vastness of the far-flung provinces there is little response. With the end of Russia's ability to use force as they once did under the Soviet Union, not much he can do about it when everyone else in the world tells him to go pound sand.
Mugabe is finished in politics in a few years and Putin's not going to rule until he's 90. Whatever comes next will come from Putin's camp but that person could be as different to Putin as Boris Yeltsin who nominated him.
well of course putin is not going to literally become 'president of eurasia'...but he does largely have the ability to force his will on europe by coercion...and that is one of his major ambitions...
robert mugabe is almost ninety and he shows no sign of giving up power any time soon...putin is no different...
in any case putin's successor is likely to come from the same chekist camp as putin...
and yes the intimate relationship between the russian orthodox church and putin's regime has been very bad for religious freedom...the russian government is deeply biased against protestants and anyone who is not russian orthodoxist...
it is really unlikely that the russian orthodox church will close their rift with rome...the russian orthodoxists are far too arrogant and imperialistic to reunite with the roman church on any lesser terms than the patriarch of moscow superseding the pope...
