Except from within.
Disagree? Answer my questions below, and explain exactly how you would go about attacking Russia.
Why does thinking about nuclear weapons cause most people to think in absolutist terms like this?
Maybe Russia was counting on getting a 15-minute warning of ICBMs approaching, but if a hostile military can station missile right on their southwestern border (523 miles from the center of Moscow) their plan goes out the window.
USA isn't counting on a 15 minute warning either, MAD is ensured via second strike capability AFTER the first strike, if you are counting for the first strike you've already lost.
See: the Cuban Missile Crisis:
https://en.wikipedia.org/wiki/Cuban_Missile_Crisis
In any case, even in a MAD setting every side will be constantly trying to manoeuver to a position of advantage. That's what military people do when they're not actually fighting, kind of how computer nerds play video games when they're not coding, eh?
But on second thought, I concede that the shortened warning time relative to ICBMs is probably not a major cause of Russia's anxiety about Ukraine.
I don't understand the question. Can you elaborate?
How would you go about invading Russia, as a senior NATO commander? Russia's stated policy is to deploy nuclear arms against any invading force.
As for a hypothetical sneak attack on Moscow, are you familiar with the concept of the strategic defense triad?
I'd take advantage of Russia's folly of invading a neighboring country and use that opportunity to destroy Russia's military forces, all while hampering their ability to rebuild that materiel.
Meanwhile, I'd have anti-ICBM technology in place so if Russia did try to launch, it would be largely ineffective. Besides, if Russia did try to launch, they'd lose the few allies they have, save for North Korea. It would probably also ensure Siberia leaves - and at that point Russia would be powerless to stop it.
What I don't need to do is invade Russia.
NATO would have to nuke Russia, then invade. Tank crew are protected from fallout radiation. If they have filtered air, I think they can enter "fallout plumes" right away. Soldiers not protected by tanks will be able to enter in about 3 weeks: weapons fallout is very different in character from the contamination from, e.g., Chernobyl or Fukushima. It dissipates much more rapidly. In fact, since the fallout plumes will cover only about half of the land area or less, the tanks can map out the locations of the plumes, after which the infantry might be able to enter the parts of the country missed by the fallout plumes well before 3 weeks after the end of the nuclear attack. (The fallout stays in one place after it has fallen out of the sky and has hit the ground -- or more precisely the fallout that does end up being blown around by the wind after it has hit the ground is small enough in particle size to not be deadly, though it will mess up your mucus membranes via beta radiation, hence my words above about filtering the air for the tanks.)
When Jens Stoltenberg says that a nuclear war cannot be won and must never be fought, his "cannot be won" is not literally true. He is saying it to emphasize that NATO would never even consider starting a nuclear war. And in fact I don't think the US or NATO ever would choose to start an intercontinental nuclear war, but it is very hard for the Kremlin to come to understand the US well enough to be as confident of that as I am (having lived in the US for over 60 years). Also, the people who run Russia and who will run Russia after Putin is dead are professional spies. They are evaluated by how seriously they take national security. Also, Russia has been invaded about 50 times in its recorded history: by the French, the Germans, a Polish-Lithuanian confederation, Sweden, the Turks many times, various groups (other than the Turks) looking to get slaves, Central Asian peoples and many kinds of steppe nomads (mostly notably the Mongols, Tatars and Cossacks). The whole country takes national security very seriously.
Of course NATO would want to evacuate its cities before it begins its attack. If it does, more than half of its population will survive the inevitable Russian response -- probably much more than half. (It's been a while since I saw the relevant papers.) Also, the US has spent many tens of billions on research into missile defense, and Russia cannot know with any certainly whether that research has born enough fruit so that the US can shoot down most of Russia ICBMs in a big war. Also, the Kremlin has expressed concern that the US Aegis system can shoot down Russian ICBMs, and now that Ukraine is good buddies with NATO, Russia has to consider the possibility of NATO's stationing many Aegis systems in Eastern Ukraine in addition to the Aegis systems already on US destroyers in the Baltic Sea.
In 1951 or so, China sent an army of about a million men against a large number of soldiers of the US Army. This Chinese army had the usual instructions from its political masters, namely, to kill as many US soldiers as possible and to destroy their equipment. They did this even though they would only get their first nuke in the 1960s whereas in 1951 the US had hundreds of nukes. Although the events I just described are a far cry from China's invading the US homeland, it does go against the notion that nukes are somehow a magical shield against conventional military attacks if even a non-nuclear military will contemplate attacking a nuclear power.
By the way, consider the motive of Beijing in 1951: the reason they risked getting nuked was to avoid having a regime (namely, the regime in Seoul) friendly to the US on their border. They preferred having a buffer state, namely, North Korea between them and any country friendly enough with the US to maybe agree to host US troops. They preferred it so much that they sent a million men and risked getting nuked. That is one of the data points that led Mearsheimer, Kissinger, Merkel, Sarkozy and many other security experts to criticize the plan of adding Ukraine to NATO. (Merkel and Sarkozy stopped their criticism because Paris and Berlin depend on Washington to guarantee their security, which gives Washington the last word on Paris and Berlin's security policy, so they went along with the plan even though that thought they still thought it was dumb.)
NATO threat to Russia is internal fear-mongering propaganda and I have no idea why Mearsheimer and others talk about it with a serious face. We're not in the middle of 20th century anymore.
On one hand we have EU/US/NATO intelligence saying Kiev will fall in 72 hours to the 2nd best army in the world.
And then on the other hand we must believe Mearsheimer that Putin really fears that EU/US/NATO would start a war out of the blue with a country that has 45% of world's nuclear arsenal in the middle of Europe?
Give me a break.
No one sane in Europe is interested to start a war with Russia.
Europe and especially Merkel have spent the last few decades turning Russia into an important trading partner and tying them heavily into the European market. This worked well for them with the economic union post World War 2 (that turned into the European Union) which stopped wars in Europe for almost a century.
Similar approach was taken with Russia, but sadly it didn't work.
Russia has every right to fear NATO and make plans around it. But to say Russia invaded Ukraine because of NATO (or nazis) is nonsense.
I don't believe you'll even find any Russian opposition/anti-government journalist/scientist/economist or politician talk the "NATO threat" reasoning seriously. They know what Putin has been doing to their country for the last 20+ years, and it has nothing to do with NATO.
Russia wants to regain its "lost" territories, started with annexation of tchetchenia (2 wars), annexation of parts of Georgia, and annexation of Crimea. Ukraine was next regardless. They already annexed the break away republics of Ukraine, and even land that they since lost.
No need for pretexts (NATO, denazification, biolabs, or protection of Ukraine ethnic Russians) to explain Ukraine invasion. Ukraine not ruling out joining NATO meant they had to invade while they could, or let go the dream of a glorious Grand Russia.
I mean, they don’t even hide it, it’s all over their state TV networks, with propagandists telling things like "Europe will be ours", "To Berlin", and "The world belongs to the superior Russian race". It’s textbook fascism, state-sponsored, casual, on modern TV shows. I find it disturbing that some still think they are the victim and it’s all about NATO imperialism. When was the last time some NATO country annexed some land?
Give me a break. You can throw a rock from Estonia and hit Saint Petersburg, look at a map of the area sometime. Estonia has been in NATO for over 15 years or something like that. Somehow Russia's been ok with that situation so far as to not start a shooting war over it.
This war with Ukraine is purely a war of aggression based on a Russian chauvinistic narrative of history. Putin explicitly says so in his writings, e.g. "On the Historical Unity of Russians and Ukrainians".
