That's the politicians point of view. I think it's VERY debatable that Australia's M1A1 are NOT the "best" tanks in the world, however they ARE very good and definitely amongst the best in the world, which should be saying enough...
Hey, our universities have done very well with producing some very fine lawyers. When I was in college I had a Prof. who taught at our "law school," but was unique in that he found the time to bless us students who were/are the prey of his regular students, by fitting us into an "international law" course. It was very much his own version of "International Law." What was funny was that I walked into his office one day, and while I was talking to him, I saw two things I'll never forget (one of those moments). One, was a small statute of a an old man sitting in a chair, and the base of the statute read, "Got a problem? Sue the F***IN Bastard"! The other was a plaque on his desk that said, "The Total Value of the Invention of the Printing Press is found in the "Fine Print"!
Needless to say, we have a nation of Lawyers who will sue/defend anyone they can for literally anything. However, americans have learned some "Fine" marketing skills (needing to sell w/o being sued), e.g. The M1A1--
The Best Tank In The World! ® Just another name for the tank... didn't even say, "...entire world" (lawyers' speak and marketing dream)! The M1A2--
MULTINANO® HYPER-POWERII® PLANETARY-DWELLER ®! Sounds great, I'd want one! But like most things in the US, just make up some BS words, create and sell to a market and stick the disclaimers in the "Super Fine Print."
Didn't want to get that off the topic, but it is amusing to see things printed like that, with "USA" behind it. Obviously this is not to say that the M1A1 isn't a great tank (it is)... it's just that we haven't ever made something that's not the best in the world?
