He's a master of mass-media communications. I thought I saw a couple of MPs crying at the video.
From yesterday, at the New York Times, "Quoting Churchill and Shakespeare, Ukraine Leader Vows No Surrender":
In a dramatic video address to Britain’s House of Commons, President Volodymyr Zelensky of Ukraine said he would never capitulate to the invading Russians. LONDON — With Ukraine’s outgunned army holding firm despite Russian bombardments that have displaced millions of civilians, the war in Ukraine has become a grim spectacle of resistance, no one more defiant than the country’s president, Volodymyr Zelensky, who vowed on Tuesday never to give in to Russia’s tanks, troops or artillery shells. In a dramatic video address to Britain’s Parliament, clad in his now-famous military fatigue T-shirt, Mr. Zelensky echoed Winston Churchill’s famous words of no surrender to the same chamber at the dawn of World War II as Britain faced a looming onslaught from Nazi Germany. “We will fight till the end, at sea, in the air,” Mr. Zelensky said with the blue-and-yellow Ukrainian flag draped behind him. “We will fight in the forests, in the fields, on the shores, in the streets.” The speech, the first ever by a foreign leader to the House of Commons, was the climax of Mr. Zelensky’s darkest-hour messaging to fellow Ukrainians and the world in what has become a typical 20-hour day for him in Kyiv, the besieged capital. In his daily speech to the nation, he claimed that Ukraine had inflicted 30 years of losses on Russia’s air force in 13 days. And in an internet video posted Monday night from his presidential office, he all but taunted President Vladimir V. Putin of Russia. “I’m not hiding,” Mr. Zelensky said. “I’m not afraid of anyone.” Nearly two weeks into Russia’s war, it was becoming ever clearer that the Kremlin’s military planners, not to mention Mr. Putin himself, had dramatically miscalculated not only the grit of Ukrainian resistance but also the calamitous economic consequences for Russia, which on Tuesday faced a major new embargo of its oil exports and a growing exodus of large American companies. At the same time, the scope of the humanitarian disaster across Ukraine was growing by the hour, as were the reverberations among its European neighbors. Russian forces continued to batter Kyiv and other cities. In Mariupol, a strategically crucial port city surrounded by Russian forces, hundreds of thousands of people remained trapped without water, electricity and other basic services. In his speech to British lawmakers, Mr. Zelensky reiterated his plea for the NATO alliance to impose a no-fly zone over Ukraine, something NATO leaders have ruled out because they fear it would could trigger a wider military clash between the West and Russia...
