Not as much difference as you might think.
As a defence force the more countries involved with a similar outlook, the less chance of problems, and, or erm, wars.
With just usa as our ally we are just a defence outpost, told to jump and follow orders. Nothing more! Russia, and, or any other country would have to get past us to get to the Usa east. I prefer more of a say in our defence.
Yes but it isn't controlled by one centralised government, each member has its own freedom to control it's own army.
The two are not the same.
