or starters... australia and usa have the anzus treaty, which means if a country goes to war against us, the usa goes to war against them, the usa gives us hundred of planes and equipment.. look it up lol... georgia started a war... australia wont...
secondly.. umm yess big muscles do make muscles stronger as their is more muscle fibre to contract... it all comes down to conditioning though, sure you can get smaller guys who are very very strong and sometimes stronger then guys with arms a lot bigger then them, but if you get a 70kg guy who is extremely strong, and a 120kg guy who is also strong.. the bigger guy will be stronger, because a human can only really lift around twice their body weight... how can 140kg match 240? lol... and yes australia has won medal sin weightlifting.. and im still to see a chinese athlete who doesnt use performance enhancing drugs.. even your women swimmers are built more then 3/4 of your male population.. women cannot achieve that without steroids etc..... one again china cheat lol.. it something they built their whole civilization around lol
