AFAICT we don't disagree on any points. Regarding support for Yunukovych, the deal was signed and not followed up on. It's true his authority was fading fast - these things are not mutually exclusive. The Feb 21 deal was struck to resolve the standoff discussed in your linked NYT article - can you point to where it says that annexation began before Feb 21st (the earliest I can find it mention is March)?
Similarly with covert armaments - the discussion of 'too much to ask' or 'right or wrong' is orthagonal to whether the West takes covert action in the Baltic to achieve policy objectives. My claim is merely that it is done - not that it is wrong.
And similarly wrt the association agreement - it has to do with the context of EU and NATO encroachment and Western action in the Baltic (I would have to admit that it was EU membership, not NATO, in this case).
The grandparent may have anti-European or -NATO sentiments. I don't. But I will defend the idea that the West, having heavily polled Ukraine and called for its own elections, and having discussed options for replacing the leadership, and training and funding groups in the Ukraine, and having controlled the election process in Kiev (calling afoul when Russia performed the same in the Crimea) absolutely is not above influencing its own support. Again I am not calling this bad.
