Well, yes and also no. Ongoing violence usually wears itself out but the root causes of some wars remain unresolved and cause lasting problems for geographic regions down the generations. The Korean war is technically still ongoing and neither state recognises the other. The Turkish invasion of Cyprus was 50 years ago and has never been truly sorted out, the ethnically Turkish inhabitants of the island live as international pariahs as their 'nation' is unrecognised by anyone but Turkey.
There's also a little matter of the Middle East, which has seen a few wars involved Israel officially end, but that's hardly brought any lasting peace to the region.
In light of the ongoing conflict in Ukraine, I would suggest that it is important to recognise the historical parallels between Putin's actions and those of past aggressors like Hitler. Both leaders sought to expand their influence through force, undermining the sovereignty of neighbouring nations. The reality we face today is that the imperialism driving Putin’s regime cannot be contained through negotiations or appeasement alone. He has demonstrated this.
Some dont want to, or wont see it this way, but the only way to effectively end this war and deter future aggression from Putins regime is through a decisive defeat of his ambitions. Just as the defeat of Nazi Germany was necessary to halt its expansion and restore peace to Europe, so too must the international community, especially Europe, remain united to challenge and dismantle Putin's imperialist agenda.
This is not only about defending Ukraine but the principles of freedom and democracy that underpin the free world - and the rights that those before us fought for. History has shown us that tyrants will only be emboldened by weakness. Sadly, the only choice the west has is to stand firm and ensure that this conflict does not become the prelude to a larger crisis.
Only through maintaining our support and resolute action can we hope to secure a lasting peace and address the resurgence of authoritarianism in our world. That is the choice Putin is presenting us with.
