It is better to put an end to Russian President Vladimir Putin's war strategy now before his aggression is spread to the other territories, President of Ukraine Volodymyr Zelenskyy said in his speech at the World Economic Forum in Davos on Tuesday.

"The full-scale war in Europe has been ongoing for nearly two years. Counting the time since Russia's illegal annexation of our Crimea, it's been almost 10 years. And for almost 10 years, Russia has been interfering in African countries, from Sudan to Mali. The Syrian war, still bleeding because of Putin's decision to prove something to the world, has been ongoing for almost 13 years," he said.

Zelenskyy also said Putin "has stolen at least 13 years of peace replacing them with pain, pain, pain and crises that impact the entire world. Putin is trying to normalize what should have ended in the 20th century – mass deportations, cities and villages razed to the ground, and the terrifying feeling that the war may never end."

"In fact, Putin embodies war. We all know that he is the sole reason why various wars and conflicts persist, and why all attempts to restore peace have failed. And he will not change. He will not change," he said.

"And he will not change. He will not change. We must change. We all must change to the extent that the madness that resides in this man’s head or any other aggressor's head will not prevail," the president of Ukraine said.

Zelenskyy emphasized that "Putin is frank about what he wants, what he does, and who his targets are. His answer to the limits of chaos in the world is the boundless support of terrorist forces. He enjoys conflicts that cause suffering to others."

"Regimes like his exist as long as they wage wars. And we – we all in the free world – exist as long as we can defend ourselves. If anyone thinks this is only about Ukraine, they’re fundamentally mistaken," he said.

Zelenskyy asked, addressing the participants of the forum, which European nation today can provide a combat ready army on par with that of Ukraine, holding back Russia.

"And how many men and women are your nations ready to send to defend another state, another nation? If one must fight against Putin together in the years ahead, isn't it better to put an end to him and his war-strategy now, while our brave men and women are already doing it? They are the world’s chance. They are," he said.
