I'm told coordination efforts with, for example, inferior air forces, are often more costly than doing it alone. Compare it to coordination efforts between, say, Microsoft's marketting department and a local food blogger. They don't operate using the same methods. Ohh, and US defending Europe, the best example: the cold war. It was decades of US military buildup largely to ensure they could invade or nuke eastern Europe if they invaded first. South Korea is another example of a military that is smaller because we keep a potential invader away.
