And yet the past two weeks have revealed a lot.
First, how Russia neutralises potential threats and pressure points.
Kremlin critics would put this another way: how Russia plays for time.
On 10 May (a few hours before I got lost in the Kremlin), after a phone call with Donald Trump, European leaders had issued an ultimatum to President Putin: agree to an unconditional long-term ceasefire in Ukraine in two days or face crushing new sanctions.
Since March the Trump administration has been calling on Russia and Ukraine to accept a 30-day comprehensive ceasefire. Kyiv agreed. Moscow hasn’t.
The Kremlin leader sidestepped the European ultimatum with his counter proposal of direct talks in Turkey. The idea was greeted with scepticism in Ukraine and across Europe. But it was enough to placate Trump and convince him Russia was serious about wanting peace. He was all for the talks. “Crushing” new sanctions were delayed.
Ahead of the Istanbul meeting on 16 May, President Trump gave the impression that Vladimir Putin might attend. The Kremlin leader did not, sending instead a comparatively low-level delegation that once more rejected the idea of a long-term ceasefire. But, again, the modest results of the talks were sufficient to persuade the US president that progress was being made.
Then came the Trump-Putin phone call on 19 May.
By the end of it, Russia had still not agreed to an immediate comprehensive cessation of hostilities. Instead, according to President Trump, “Russia and Ukraine will immediately start negotiations toward a ceasefire and, more importantly, an END to the War”.
But Moscow is already casting doubt on whether it would sign any future peace treaty with Ukrainian President Volodymyr Zelensky. For a year now the Russian authorities have been attempting to delegitimise Ukraine’s president since the expiry of his presidential term. However, Ukraine’s Constitution prohibits the holding of elections in wartime.
And the reason for martial law in Ukraine is Russia’s invasion.
“Would Russia sit down and sign a peace agreement with President Zelensky?” I asked Russia’s foreign minister Sergei Lavrov on Friday.
“You’re putting the cart before the horse,” Mr Lavrov replied. “First we need to have a deal. When it’s agreed, then we will decide. But, as President Putin has said many times, President Zelensky does not have legitimacy… Probably the best option would be new elections…”
