So how many countries has Australia conquered lately?
I've trained with the Aussies, and they're every bit as reliable an ally as England itself. Australian SAS has had some enviable escapades in Afghanistan, and I'd trust the entire Australian military on my flank without reservation. Its not necessarily about having the ability to invade a country like we can, but what they can do with what they have...
Beyond that, I was in Australia shortly after 9/11, and those folks down there were buying us beer and encouraging us to go raise hell and get our revenge. It was an impressive sentiment and one I'll remember for life. So, if you're of a mind, seems like an awesome deal... Generally speaking, there are very few places in the world that like Americans implicitly--Australia is one of them. I'd serve with those guys and gals any day.
