This war between Russia and Ukraine is one in which a pragmatic leader could call to an end for the  sake of his people. For Ukraine there's no further need for Zelensky to still trying to push hard, find ways out to talk with Vladimir Putin, not as a show of weakness but as a pragmatic leader.

Cause looking at the politics here you'll find out that neither has NATO placed an imposition of No_Fly Zone or has the United States of America cease from buying Russian oil amidst the war. It's quite apparent as to their reasons why (National interest).

All we hear from the Western media is deception upon deception as to how Ukraine is still stand tall, resilient, and unperturbed. While to the best of my knowledge not a single missile has been fired into Russia from Ukraine soil. For no level of aid requested by Zelensky can salvage the situation.

However, even if Putin is charged with war_crimes. What is the tendency of capturing him and have him answer to charges of war_crimes? Is it same NATO countries that depend strongly on Russia oil and gas?

Zelensky should consider himself to have been fooled by the Western countries, including NATO member countries and, should fall back to Putin to find amendable ways to end this war, irrespective of how humiliating and abase it might seem, cause a CEASE_FIRE for him and his people is better than a feeling of abasement.

Most times, it's advisable to view issues from different lens.
