reductio ab hitlerum

Apparently at one point during his conversation with the US president, the Russian premiere invoked that the invasion of the Crimean peninsular was executed for the protection of ethnic Russians living in the area. Immediately, this elicited a petition by many Russians and Russian-speakers residing there, refusing those overtures, stating they needed no protecting and felt, on the contrary, very secure and welcome.
Though no further violence has actually yet been perpetrated with the occupation of the region, the next maneuvers are unclear, and I am sure that someone, somewhere has pointed out the obvious, said the argument that's no popular or considered logically flawed, but isn't this current reasoning parallel at least to the invocation of “protecting the ethnic Germans” in 1939 in Gdansk in Poland or in the Sudetenland in Czechoslovakia, Japan declaring Korea a protectorate in 1905 before formally annexing the country in 1910, or the acts of others that one cannot call to the carpet, not to mention dozens of trespasses committed in the name of US interests and for earlier empires? This invasion was premeditated and not a spontaneous response to an opportune moment of civil disarray and the defanged counter-balance is left with few tenable options, even in terms of economic sanctions—considering Europe's dependence of Russian natural resources and especially allied China's favourable assessment of Russia's actions, able to levy painful usury as the financier-in-chief of the world's accustomed lifestyle. Ukraine, despite the odds, could however offer resistance, having a respectable arsenal in comparison regardless of the spread of their antagonist, but this possibility is being decimated by Russians recruiting Ukrainian force individual by individual, luring them away with a passport and citizenship.
