Isn't Ukraine to blame for derailing the NATO membership?

We are talking about a key component of the former Soviet Union, with a big chunk of their population being pro-Russia, as they share much of their history with Russia, so even before the soviets they were part of the Russian Empire and of the Kievan Rus' state. Don't get me wrong, I've very sympathetic towards Ukraine's citizens that are pro-EU, however if I'm seeing any country having problems in joining NATO, it's definitely them.
