In reality, it’s not that hard to picture Putin and Trump meeting, shaking hands, and announcing that they’ve reached an agreement on a ceasefire. Problems, however, may arise already at the implementation stage.A ceasefire has two major stages: political and technical. First, politicians agree on a decision. But the actual ceasefire is achieved only after the technical details and procedures are coordinated and implemented.The first such question is: along which line will the fire stop? For example, whose zone of responsibility will Chasiv Yar fall into—a town Russia claimed to have captured a few days ago, but which the Ukrainian General Staff did not confirm? Even this question could, if not derail the truce, then at least seriously complicate it.After agreeing on the line of demarcation, the next step should be the creation of a demilitarized zone—that is, a territory several kilometers wide on both sides of the line. Within this area, one could, so to speak, build fortifications, but the accumulation of troops for an offensive would not be allowed. Who and how will control this is yet another complex agreement.The third issue is the handling of disputes and incidents. There must be a neutral party to consider accusations of ceasefire violations and make decisions recognized by both sides. Such a commission needs to be created and given powers that everyone agrees on."In other words, even after a political decision is reached, coordinating the technical details can take months, if not years. The experience of the Korean War shows: as long as these processes continue, fighting does not stop and people keep dying."And this is without even mentioning security guarantees: who will defend Ukraine if Russia violates the agreements?Therefore, we shouldn’t overestimate the processes that now seem like a breakthrough. Putin could announce a ceasefire even today—this would allow him to ease pressure from the U.S. But this would not be peace. And there is a risk that Donald Trump would consider his mission accomplished—and switch to another topic.It’s easy to start a war, but extremely difficult to end one. Russia has no exit strategy, so its basic approach is a war without end. And if anything does change, it’s unlikely to happen anytime soon.In other words—don’t stop supporting the military, joining the ranks of the Armed Forces, and donating to all volunteer fundraisers. Now is definitely not the time to relax.SourceAbout the author: Mykola Kniazhytskyi, journalist, Member of Parliament of Ukraine.The editorial board does not always share the views expressed by the authors of blogs or columns.
