KYIV, Feb 15 (Reuters) - How long can he keep it going?

Night after night, Ukrainian President Volodymyr Zelenskiy delivers rousing video addresses, rallying his troops in their fight against the Russian invaders and trying to keep the world's attention focused on his nation's plight.

He has successfully lobbied the West for arms, lifting taboo after taboo in the process -- initially on the West sending lethal aid of any kind and more recently on Western deliveries of battle tanks that may help Ukraine mount a counter-offensive.

Zelenskiy, now 45 and in power since 2019, shows no sign of letting up.

Nor does Russian President Vladimir Putin, who launched his "special military operation" in Ukraine on Feb. 24, 2022 and appears to be preparing for a long war.

When Russian troops poured over the border, few predicted the transformation in Zelenskiy, a former TV comedian whose trust ratings had been waning as public anger rose over widespread corruption, economic malaise and bad governance.

In the buildup, as Russia massed forces on his borders, he had criticised foreign embassies and companies for leaving Ukraine, saying they were hurting the economy and - in public at least - appeared to play down the threat of a major invasion.

He is now a household name around the world, a symbol of Ukrainian resistance. In Ukraine, his popularity ratings have almost tripled and are unusually stable.

Easy-going and relaxed when meeting newcomers in his heavily fortified headquarters, dressed in military khaki whether meeting royalty or visiting soldiers near the frontline, Zelenskiy projects an image of steadiness and steadfastness.

He has huge milestones still to clear. He is yet to secure supplies of the sophisticated Western fighter jets he says are needed to push back Russian troops, or promises of fast-track membership to the European Union. Joining the NATO military alliance still looks out of reach.

But though sometimes puffy-faced, with lines under his eyes, there is no indication he is running out of steam, and last month he launched a government shake-up to quash a public outcry over a corruption scandal.

"Zelenskiy surprised many people ... They underestimated his leadership qualities," said Volodymyr Fesenko, a Kyiv-based analyst who said Putin misjudged Zelenskiy.

"(Putin) prepared a special operation not a full-fledged war ... because he thought Zelenskiy and the Ukrainian army were weak and that they would not be able to put up lengthy resistance. This proved to be a mistake."
