European and Ukrainian security will be guaranteed with peace and renormailzed economic relations and development rather than continued adversarial relations. To draw down the knife fight both sides need put away the blades.
Deng Xiaoping compared the process of Chinese economic development to "crossing the river by feeling the stones". Developing peace is a comparable process that requires people to take an affirmative first step and continue walking across the water though they can't see what is below.
Peace between superpowers is based to a certain extent on trust. Like the value of the dollar based on nothing more than the faith and credit of the United States rather than gold or some other material, peace can only be as strong as trust and respect for other nations. One need put effort into building peace and renormalizing relations between Europe, Russia and the United States directly.
At the super-power level trust needs to be the deterrent to war. When each side can obliterate each other there is no value in engaging in battle at a conventional scale that easily can get beyond control resulting in the end of human civilization. Clemenceau wanted to guarantee the peace for ending World War One, and it wasn't, and World War Two grew to fruition. That paradigm is however anachronistic. There is no Maginot Line that will prevent World War Three.
