For what reason?...
There have been successive heads of the Russian state making it clear that a restoration is impossible and after a while, you would think she would give up.
Realpolitik: "
a policy of political realism or practical politics, that is, the politics of the real word rather than politics based on theoretical, moral, or idealistic concerns."
examples:
A restoration in Serbia is unlikely, yet Crown Prince Alexander has an accommodation with the government;
A restoration in Albania is unlikely, yet Crown Prince Leka has an accommodation with the government;
A restoration in Romania is unlikely, yet King Michael has an accommodation with the government;
A restoration in Germany (or Bavaria or Württemberg, or Waldeck-Pyrmont for that matter) is unlikely, yet the Heads of those Houses have accommodations with their respective governments...
These officials in Russia, many of them are the descendants to the people who lined her relatives up against a wall, without a twinge of regret.
Oh please, the irrational and emotive hyperbole. Using your logic, Maria Vladimirovna should shun contact with any member of the House of Windsor descended from the King who coldly abandoned the Tsar to his fate, or any person who is a descendant of someone who waged war on Imperial Russia and thereby directly contributed to her dynasty's downfall. And since when has Vladimir Putin been held personally responsible for the Imperial murders at Ekaterinburg, Alapaievsk and St Petersburg?
Apart from that nonsense, I doubt that you have any personal knowledge whatsoever of the Grand Duchess's twinges or lack thereof.
