A more accurate description of the way the world is trending:
US / UK / Europe / Japan / South Korea (still tied by defense, if push really comes to shove) vs Russia vs China vs Non-Aligned Nations (India, Indonesia, Egypt, Bangladesh, Pakistan, Ethiopia, Nigeria, etc.)
And historically (1960s), in a multi-polar world, middle powers are best served by being ambiguously aligned to force advantageous courting by major powers.
