Says you. Thank God you weren’t a British subject in 1775. You’d have been a Tory.
Again, you are equating a secession from a distant colonial power, on enumerated grounds, following acts of mutual violence, to which the king could have given a peaceful response but instead responded with military force, -- to a hastily put together farcical referendum under occupation by the very power whose legacy Ukraine is desperately trying to shake off.
The anti-Communist revolution in Ukraine indeed can be likened to the anti-colonial American Revolution. The secession of Crimea under the present circumstances can only be compared to, hypothetically, if one state of the Union, having been a part of the USA for 40 years and without being provoked by the US, would decide to go back to be a British colony and invite British forces on its territory.
Note that I am resorting to any personal characterization. Them's the historical facts.
