As long as Russia continues to violate the sovereignty of its neighbors, NATO will continue to expand to those countries which want protection from Russia's ravenous and insatiable imperialism.==
The increasing of NATO do not increase the security but otherwise dicrease it. I will prove it.
Since Russia needs to prepare herself against threats which this NATO encirling brings then Russia builds more formidable weaponry.
If as you say those countries wants protection then I don't understand HOW NATO may protect them against just one Topol-M missile with 100M warhead? Just one missile and any NATO country is surely dead.
And then you in America will have HUGE dilemma on your hands. To start whole thermonuclier war with Russia which surely brings "unacceptable losses" to America may be deaths of your beloved parents and children. OR just let it be.
I presume you will choose the second. That is the end of NATO.
Russia is not threatened by NATO, why do you think that?
What is the purpose? Can you describe a possible scenario that would cause an attack against Russia?
The major problem in Russia is the lack of trust in their own laws, and the implementation of them. Today when the oil price is at its peak the Russian government is accumulating a lot of money, they should use it wisely. In a couple of years the dependence on fossil oil will decrease together with the money.
