In September of 2014, Putin boasted that if he wanted to, he could take Kyiv in 2 weeks.
As of tomorrow, thanks to February being the shortest month and 2022 not being a leap year, it'll have been 1 month since the Russian invasion began, with an early offensive against the capital (located close to the Belarusian border) having providentially stalled after a short time.
I'm no military strategist. However, ideas are arguably as powerful as bullets. Now, Zelensky could decide to capitulate tomorrow. But assuming this doesn't happen, and depending on how long the Ukrainian army can keep dragging this out, this is a timetable spelling out some of the implications of a long war:
March 31: The Ukrainian army and government will remain yet unsubdued at the end of the same length (35 days) that it took Nazi Germany to seize Poland, despite 80 years of technological and warfighting doctrine advancements.
Granted, the Nazis actually found Poland to be a difficult foe and they might not have won had the Soviets not invaded from the east at the same time, but popular culture imagines Poland to have been a pushover with outdated cavalry charges against German tanks. As such, expect negative comparisons between the Nazi and Russian war machines to flood the internet beginning around this time.
April 7: The Ukrainian government and army will remain yet unsubdued at the end of the same length of time (42 days) that it took the US to conquer Iraq in 2003.
On the eve of Russia's invasion, one of the biggest risks was that a 21st century "lightning war" against Europe's poorest and most dysfunctional country would serve to promote the Russian military as hyper-competent, and indeed, somehow superior to the "decadent" American forces that recently lost a 20-year counterinsurgency in Afghanistan.
If Kyiv holds out until and ideally past April 7, that notion will be much easier to dispel. And with that, the risk that Russia might grow drunk in its newfound sense of invincibility and feel emboldened to soon attack another neighboring state will also be minimized. Whether Ukraine lasts another 2 weeks could help decide the future of Europe.
April 24: The observance of Easter, as the date is calculated in the Eastern Orthodox Church.
If the global orthodox community outside of Russia takes the opportunity to condemn the ongoing war and formally take a stand with Ukraine, it'll be a major challenge to Moscow's credentials as the head of Orthodoxy and serve to ecumenically isolate Patriarch Kirill, hopefully putting serious pressure on Kirill to rehabilitate his image by turning against the war.
Given that more than 3.5 million Ukrainians are refugees abroad, including in majority-Orthodox countries like Moldova, Romania, Bulgaria, and even Serbia, and given that this number will certainly rise or even double in the next month, the presence of these sympathetic refugees who've lost everything because of Russia could sway these countries' Orthodox churches to finally issue statements condemning Russian invasion.
At Easter, expect high profile statements against Moscow's war by dissenting priests inside the Russian Orthodox Church as well.
April 29: On March 12, it was reported that Russian military equipment losses amounted to more $5 billion dollars. Assuming that rate of loss can be sustained, then by April 29, or Day 64, that figure will have risen to $20 billion dollars. Of course, this doesn't count the combined daily operational costs of 64 days of war, which by this time will likely stand around $30 billion dollars.
In comparison, Russia's annual military budget is around $70 billion dollars.
May 9: The celebration of Victory Day in Russia and other post-Soviet countries.
Putin likely hopes to end the war before this date, so that on it he can celebrate the fresh "de-nazification" of Ukraine that's supposedly analogous to the de-Nazification of Eastern and Central Europe at the end of WWII 77 years ago. This opportunity will be missed.
Outside of Russia, Victory Day implicitly celebrates the role of Russian leadership in defeating German aggression. However, the ongoing 2 and a half month war of aggression against Ukraine by Russia will cause many to question why they're still celebrating this holiday.
If some countries remove the holiday's official status afterward, or do so before May 9 so that it's not observed in 2022, this'll mark a visible unraveling of the very ideal of a post-Soviet sphere.
And so, in summary, a war lasting "just" 2 and a half months longer could cost Russia:
-More than the equivalent of $50 billion dollars in military costs alone
-Its cultural influence as head of the historic bloc that saved Europe from Nazism
-Its religious influence as current head of Eastern Orthodoxy
-Its long-held reputation as a military power that credibly rivals the United States
