Saying something and believing it are two different things. Also, it depends what you mean by 'no different'. Ethnically they're almost identical. Culturally close. But there is a bit of a difference, mainly that much of "Ukrainian" identity comes from regions that had been been invaded by both Poland-Lithuania and Austria-Hungary and spread to the rest of the country since independence.
Anyhow, not even the Ukrainian President thinks Russia will invade all Ukraine...
The word you said was "attempted" which includes failed attempts as well as successful. There have been no successful attempts post-WW2 that I can think of, but that doesn't mean there haven't been any unsuccessful attempts.
> Ethnically they're almost identical. Culturally close.
You can say the same thing about the US and Canada. Yet Canada successfully resisted both US invasion attempts, and even today, you would likely get a pretty vehement response if you suggested that the US and Canada ought to be part of the same country.
I live in Alberta... That statement is definitely not true lol.
Plus, given the political issues involved with integration of the two countries, I suspect serious concessions would need to be made by Canada.
And Canada's not the liberal paradise people think. We're leaving, personally.
The quality of life here is pretty shit - think LA or Seattle cost of living (SF if you're in Vancouver or Toronto) with Nebraska wages (actually that would be generous)...
Saudi Arabia invading Yemen. Syria invading Lebanon is I think around the ⅓ mark. Iraq invading Iran--note that Iran was the larger country then. All of these are conflicts that were intended to induce suzerainty if not outright conquest, and all of these are undeniably in what you'd call the "modern era".
Although I'll note that "modern era" is usually given as since about ~1789, which means we can throw in all of the wonderful aggression conflicts that make up World War II, such as Germany attempting to incorporate the populated bits of the USSR into its own territory, after killing off the current inhabitants of course.
> they fact they were always culturally Russian.
IIRC, he claims that Ukrainians are themselves no different from Russians, which means this gives him casus belli to incorporate all of Ukraine on the same grounds.
