In the West, Moscow's intervention in Crimea has been denounced as "brutal aggression". In Vladimir Putin's mind, that is hypocrisy. He never loses an opportunity to remind the world about US intervention in Iraq, Libya and Afghanistan.
In his speech to the Munich Security Conference in 2007, Mr Putin denounced what he saw as a "unipolar world" - a world where the United States was the single master. He has been determined to defend what he sees as Russia's legitimate interests around the world - be they in Syria, or closer to home in Ukraine.
What is more, with much of Europe relying on Russian energy imports and benefiting from trade with Moscow, the Kremlin calculates that its opponents in the West will not have the stomach for a serious falling-out over Russian muscle-flexing.
President Putin maintains he does not want to go to war with the Ukrainian people. He claims Russia's intervention is "humanitarian" to protect people there from "chaos".
But Russia's national interests will be paramount for him: ensuring the new government in Kiev cannot eject the Black Sea Fleet from Crimea and that Ukraine's new leaders think twice before embracing the West and rejecting Russia.
