Open up Google maps and read my comment.
There is a small path from the Mediterranean sea to the Black Sea. This is the Bosphorus located in Constantinople (modern day Istanbul). If this path is closed, Russia cannot get their fleet anymore to the rest of the world, as that is the ONLY way out. To win something, you play step by step. Just like chess you sacrifice pawns to get what you want. But a pawn has also the ability to kill even the king. So their target is to get rid of Russia once again as USSR has collapsed in 1991. They want to do the same with modern day Russia as it has became to powerful. Just in 26 years it has already become a superpower again, while it had collapsed back then.
NATO want control over things. That which they cannot control, must be destroyed. (Such as Saddam Hussain and Ghaddaffi as two examples). Where they dictators? Yes they were. Was i fan of either one of them? Nope i wasn't. So it wasn't because they were dictators but they wanted to act against NATO by not being controlled by NATO. If you are not controlled by NATO..you will mostly join the other side (Russia, China etc.) NATO doesn't "want" control over black sea..they want to collapse Russia once again and as i have said in my other comment, Russian Black Sea fleet is located on the Crimean Island. They want to dismantle it completely.
A country not in NATO must give Russia a reason to attack. I mean why would i not want to invade your home? If there is no reason for me to..why should i? As far as i have seen by their actions, they do not seek control, they seek partnership. Have partnership that gives mutual benefit. Look up (BRICS). NATO on the other hand, they want control.

If a country does not obey NATO, they know one way or the other they will be "brought democracy"..(war) to topple the people in power in that country and replace with one who does listen to NATO.
As i said in my previous comment, the SOUL purpose of NATO was to create a alliance against USSR because it had become too powerful. USSR had their vision of conquering, but modern day Russia doesn't as far as i have seen by action. I do not listen to words, but look at actions. NATO does not want Russia to be powerful or mess with what they want things to go. For example, if you say we must do X and say we must do Y. If you are stronger than me, you just get rid of me and do X. But if i am stronger than you ..you will not able to do X.
Disobeying..well NATO will "bring freedom and democracy" to your country as they have done in many countries :).
NATO has certain rules. If one country is attacked, all the countries unite and attack the aggressor.
US cannot take Russia out, because when somebody has certain arsenal of nuclear weapons.. it will not go very easy. If you are about to die because of your enemy, wouldn't you use ALL YOUR MEANS? Why don't you think North Korea hasn't been invaded yet? Because North Korea also has the A-Bomb. Messing with a country that has the A-BOMB is NOT a good idea.
They are not friends and were never friends. USA is mostly in charge of NATO. Israel is again in charge of USA. I SUSPECT that much has to do with the end times and destruction of Israel. That is why Bolshevik Revolution in replacing Christian Orthodox Russia with Communist anti-religion Russia applied by majority Zionist Jews.
