Because Ukraine wasn't a member (only applied for membership, but hadn't met requirements) when "separtists" "freed" the Crimean peninsula to "protect" the Russian civilians "trapped" there. Shooting down MH17, a B777-200ER with 298 aboard, 50km over Ukraine using a SAM was provoked by NATO?

I think I have an idea of who will be invading, escalating, and hoping there won't be consequences.
