Thanks to the Democratic Party.
Because Russia used to be in the Council of Europe and in the G8.
But during the Sultanate, Russia was ostracized by the West, and now she becomes allied with the Communists.
Do you mean the U.S. Democratic Party? If so, then I'd have to say that's only partially true, although I would admit that the decisions to divide Korea and send U.S. forces to war in that country were both made by Democrats. However, the Republicans continued with that status quo, and even beyond that, they advocated for even a harder line against the Communists, while painting the Democrats as weak and wimpy to the point of calling them treasonous ("pinkos"). There were even internal disputes within the Democratic Party, such as during the Vietnam War era. Some Democrats wanted peace, while others wanted war. It appears that the peaceniks are all gone, and all we have left now are the warmongers. More is the pity.
It's not that much of a surprise that they would ally with North Korea. They've been allies before. The tragic irony of all of this is that, if we had taken a different approach with Russia 25-30 years ago, we could have had friendlier ties, and Russia could have been helpful in bringing in countries like North Korea and Iran into a more reasonable and stable fold. I think that could have been possible, if we really tried. Unfortunately, our leaders chose a different path and focused their attentions on the Middle East, such as Iraq and Afghanistan, while continuing to isolate Iran.
And of course, we still maintained an active military presence in over 80 countries. While it seems to come as a great shock to many Americans, there are more than a few people around the world who aren't too fond of what our government and military do around the world. And even within America, there are those who think we're going too far and that we're overextended enough as it is. If alliances are being formed against us, then we have to consider our own position and certain policy changes which might be needed to protect our territory and national interests. We have to look at geopolitics and foreign policy more pragmatically.
