We might be able to influence N Korea with these tactics, but Russia has a lot of natural resources, people and materiel. It's a diff game.
You have had (some) people on the left defending Kim Jun-un's actions as predictable (he's being bullied, etc). Putin's are predictable too, given what he has to work with.
I think we'd be better off reluctantly working with him (in the ME, for ex.) than blocking them every corner. It sets them back into a cold-war mentality. We (the world) need the biggest powers, US, CN, RU, to get along, if not be friends. We don't see eye to eye in many things (human rights wise, ex, pollution, ex) but we can work toward a more stable planet.
If anything, we can say that the current sanctions and other have been somewhat effective in deescalating violence, and if the west would have pulled back, then we'd have Ukraine dismembered by now through increased direct Russian military involvement.
Nothing "sets back" Russia to cold war mentality; they have never left it, won't will without a regime change, they won't stop treating the west as their enemy and they will aggressively (re)take the now independent states we let them to.
And, was it Russia that expanded to the NATO borders, or were the NATO borders that expanded to eventually reach Russia?
The sovereign countries themselves must get a choice - if they want to join NATO, that is their right, and Russia shouldn't get a veto (nor even a vote) in that. Countries should be free to join/leave the "spheres" at will, not be placed there or given or taken.
And, actually, the whole reason why NATO is at their borders is the Russian insistence of their sphere of influence. If Russia agreed in practice that their borders stop where they are and that they won't ever poke beyond them, then their neigbours wouldn't need to even consider NATO.
The belief in Ukraine, however, was that Russia was an ally, did not pose a threat and therefore Ukraine should have not seeked NATO membership. That assumption proved to be wrong now.
Amazing doesn't even begin to cover Americans complaining about foreign interference in our elections.
There's hardly a country up and down Central and South America, North Africa, and the Middle East whose elections we haven't meddled in. Start with the Shah of Iran, Mubarak, Hussein before he turned on us, the Bay of Pigs, Allende/Pinochet, etc.
Which is not to say we shouldn't push back on Russian interference in our elections, but just wow. I'd like to see us keep out of everyone else's elections too.
Back in those days it was more do or die. Let the soviets gain ground and grow their ideology or stop it within reason [stop short of no-proxy hot wars].
If we look at the toll paid by countries which went 2nd world vs those that stayed/coherced on our side, the suffering was much greater in those that went full soviet.
And often times people who point to Allende etc as bad will not point to Ghadafy or all the rest in N. Africa Obama set loose.
I think it's probably a bit naive to assume the US has stopped interfering in elections.
We just need to recall how we felt when they pranced around Cuba. We're doing similar in the eastern block (not the same degree) but all the same it gets in their craw.
