To understand February 2022, you have to start not with Putin, and not with NATO, but with the land itself. Russia is the largest country on Earth — eleven time zones, 17 million square kilometres — yet on its most sensitive flank, the west, it has almost no natural defence. From the Atlantic coast of France all the way to the Ural mountains stretches one enormous, almost unbroken lowland: the North European Plain. For four centuries this corridor has funneled invaders straight into Russia's heartland. Every generation of Russian strategists — tsarist, Soviet, and post-Soviet — has read the same map and reached the same conclusion: without depth in the west, Moscow is exposed. Tim Marshall calls this Russia's founding geographic problem. The Kremlin calls it survival.
Strip the map of forests and cities and look at the terrain itself. There is no barrier between Warsaw, Berlin and Moscow — no Alps, no Pyrenees, no Rhine wide enough to matter, no sea. The plain widens as it moves east: narrow at the Polish neck (only about 500 km between the Baltic and the Carpathians), then fanning out into the vast, undefended expanse around Smolensk and Moscow. An army that breaks through the Polish gap has nothing to stop it until it reaches the Urals, 2,000 kilometres later. This single geographic fact is why every serious Russian ruler, from Peter the Great to Stalin, has spent enormous blood and treasure trying to control the plain rather than defend against it. Buffer is the doctrine; the plain is the reason.
The pattern is monotonous. Charles XII of Sweden marched east in 1708 and was destroyed at Poltava. Napoleon crossed the Niemen with 685,000 men in 1812 and stumbled back with fewer than 30,000. The Kaiser's armies drove east in 1914 and pushed Russia out of the war. Hitler launched Barbarossa in June 1941 with three million soldiers — the largest invasion in history — and reached the outskirts of Moscow before winter, distance and Soviet resistance broke him. Each of these invasions arrived by the same flat corridor, and each was stopped less by fortifications than by Russian space: the sheer depth of territory that turned every advance into a supply-line nightmare. For the Kremlin, the lesson was permanent. You cannot fortify the plain. You can only push your border as far west as possible and trade land for time when the next army comes.
After 1945 the Soviet Union solved the plain by occupying it. The Warsaw Pact — East Germany, Poland, Czechoslovakia, Hungary, Romania, Bulgaria — turned Central Europe into a 1,000-kilometre-deep shock absorber against the West. Soviet divisions were stationed in Berlin, not Smolensk. Any NATO attack would have to fight through six client states before threatening Soviet soil. This buffer was the single largest strategic prize the USSR extracted from the Second World War, and Moscow paid for it in tanks, subsidies and secret police for four decades. Then, between 1989 and 1991, it evaporated. The Wall came down, the Pact dissolved, the Soviet Union itself broke into fifteen pieces, and Russia woke up in 1992 with its western border pushed back roughly where it had been in the seventeenth century. For the first time in generations, the plain was open again — and this time NATO stood at the other end of it.
In 1997, Bill Clinton's administration invited Poland, Hungary and the Czech Republic to join NATO. In 2004 the alliance absorbed seven more states, including the three Baltic republics — putting NATO troops on a border they had shared with the Soviet Union just thirteen years earlier. Albania and Croatia joined in 2009, Montenegro in 2017, North Macedonia in 2020. In total, between 1999 and 2020 the alliance expanded five times and absorbed every former Warsaw Pact country plus three former Soviet republics. Measured from the Berlin Wall, NATO's eastern frontier moved roughly 1,000 kilometres closer to Moscow. American officials described this as a voluntary process of democratic states joining a defensive club. Russian officials — including Yeltsin, Primakov, and later Putin — described it as encirclement. Both were, in their own frames, telling the truth. What matters is that in the Kremlin's reading, maps are not neutral documents. Maps are read as intent.
Of all the states between Russia and NATO, Ukraine matters most, and for reasons that are older than any current politician. Its territory closes the southern half of the North European Plain, sealing the approach to Rostov and Volgograd. Its Black Sea coastline gives Russia its only warm-water naval access to the Mediterranean — a strategic obsession from Catherine the Great onward — through the port of Sevastopol in Crimea. Its farmland fed the Soviet Union. Its industrial base built Soviet rockets and tanks. And, in the identity story the Kremlin tells itself, Kyiv is the birthplace of Rus' — the medieval Orthodox civilization from which modern Russia claims descent. Zbigniew Brzezinski put it bluntly in 'The Grand Chessboard' (1997): without Ukraine, Russia ceases to be a Eurasian empire. With Ukraine — subordinated, neutral or absorbed — it can rebuild one. This is why every serious Russian strategist treats Ukraine not as a foreign country but as a strategic hinge.
In November 2013, Ukraine's pro-Moscow president Viktor Yanukovych backed away from signing an association agreement with the European Union. Protests erupted in Kyiv's Maidan square and lasted three months. In February 2014, after dozens of protesters were shot by police, Yanukovych fled to Russia. Within two weeks Russian special forces — 'little green men' without insignia — had seized Ukrainian government buildings in Crimea. A hastily-organised referendum, held under armed occupation, produced a 97% vote for annexation. Russia formally absorbed the peninsula on 18 March 2014, locking down Sevastopol. Simultaneously, Russian intelligence supported an armed separatist movement in the Donbas that hardened into a low-intensity war, killing roughly 14,000 people over the next eight years. The intervention bought Moscow time and a naval base, but it did not solve the underlying problem: Ukraine's political centre of gravity had shifted decisively toward Europe, and the Ukrainian army had been humiliated into rebuilding itself with Western help.
At around 04:00 Kyiv time on 24 February 2022, Russian forces attacked from three directions. A northern axis pushed south from Belarus toward Kyiv, aiming to decapitate the Ukrainian government within days. A north-eastern axis drove from Belgorod toward Kharkiv. A southern axis broke out of occupied Crimea toward Kherson, Melitopol and Mariupol, seeking to cut Ukraine off from the Sea of Azov and link up with the eastern Donbas front. Putin's televised address that morning cited NATO expansion, the 'genocide' of Russian speakers, and the 'denazification' of Ukraine. The military plan, however, revealed the real objective: a rapid collapse of the Ukrainian state, replaced by a compliant regime that would take Ukraine off the Western map. The stated goals were ideological. The operational goals were geographic. Reclaim the buffer. Keep NATO off the plain. Restore the imperial hinge.
Three years on, the invasion has produced almost the exact opposite of what Moscow wanted. Kyiv did not fall in three days; the northern axis was defeated by early April 2022 and Russia withdrew from around the capital. Ukraine, previously a divided country with a modest army, has become the most battle-hardened land force in Europe, integrated in everything but paperwork with NATO logistics and intelligence. Finland joined the alliance in April 2023, doubling NATO's border with Russia overnight. Sweden joined in March 2024, ending two centuries of neutrality. Germany announced a €100 billion special defence fund within days of the invasion. Poland is now on track to field the largest army in NATO Europe. Russia's economy has been prised out of the Western financial system and increasingly bound to China as a junior partner. Whatever else 2022 was, it was the moment the Kremlin's geographic strategy produced its own worst outcome: the plain is more contested than ever, Russia's buffer is smaller than at any time since the eighteenth century, and the enemy Moscow feared most is now consolidated on its doorstep.
