But that's not what you said, you stated it hasn't happened after WW2 until now. I took that to mean that no country had invaded another country for the purpose of annexation, at all, until now. I gave an example that it did in fact happen before now. It was corrected after the fact, seven months or so at that. What you are describing as a first with Crimea in 2014 had, in fact, happened before in a similar way. It's just with Crimea so far there's been much less bloodshed. There's a difference between saying such actions have not been tolerated since WW2 and such actions have not happened at all.
