Why can not? Don't you remember how America and Japan, once enemies, became friends? nothing is impossible, this is all a matter of politics, in politics there are no enemies or friends, there are only interests.
They became friends by force after the US dropped a couple of atomic bombs on Japan, so rather than becoming friends, Japan became a vassal of the US. We could only say that they were friends on equal terms many decades after the end of the conflict.
I hope that such ways of achieving friendship will not be experimented with in this conflict.
