It's comforting to know that we will nuke Great Britain if its military ever gets larger than ours...
This doctrine will be received by much of the world as American arrogance "Not only will we defend our status as the world's sole superpower, but we'll do it because we're the kindest, most benevolent country on earth. Oh, and by the way, we're better than you are."
"It's comforting to know that we will nuke Great Britain if its military ever gets larger than ours..."
No, it means that we'll work to make sure our military remains the best, so that we won't have to put up with blackmail nor have to submit to a superior miltary force, nor have to take massive losses because we failed to remain on the cutting edge or slacked off in training. It does NOT say we'll arbitrarily attack all nations whose militaries are reaching par. It merely states that we will train hard, work steadily, study , and maintain and develop the best means to defend the country- in short, we'll remain vigilent so as not to be taken by suprise.
So if Britain wants to work hard too, that's fine. In fact, it would be great. We'll keep working just in case, so we don't have to wait for Britain to come to our rescue because we were slacking off.
