You're saying that all the colonization that occurred prior to the 20th century is OK. That's what you're saying. That it doesn't count because it wasn't from the 20th century....never mind the fact that we are in the 21st century, so applying early 20th century standards isn't even in line with today.
BTW - the exact same argument you are making against Israel, you're defending on behalf of Russia.
So you're not principled, you're just a hypocrite.
