What we need is to minimize or eliminate the adversarial relationships between nations globally. The only winners of the present status quo are the elites in every nation.
That's heavily context dependent and it's a perspective that assumes that adversarial relationships emerge because both sides did something wrong. This naive appeasement mindset in the 1930s did more harm than good, for example. If you have a rival that's revisionist and aggressive, sometimes you need less cooperation and negotiation, and more war, in order to accelerate their demise. Of course, you usually don't want that, but as I said, it's context dependent.
