Not including US (obvious, with spending of over 400 billions in military....)
Which following nation has biggest potential to develop advanced military aircraft withtout help from outside?
1. Europe (well, with Airbus and traditions of British and German....)
2. Japan (According to current military analysis, without including nuclear force, Japan has the 2nd most technological force in the world. With merely 1% of military spending and its robust economy (my Economic Prof. told me that every 1% growth is equivalent to the ecnomy of Malaysia).
3. China (The most enduring and most technological of all ancient states. In fact, according to January issue of Natioanl Geographic in 2004, Chinese were much advanced in economy and in technology than their comtemporary Roman empire. But it declined in late 17th century, and was helpless against British industrial power. But, Napoleon Bonarparte once said to his follow generals: "Let China sleeps, if she wakes, she will shake the world". China is waking, just like US a centry ago, or Japan 50 years ago, but it is much bigger. Many economists describe current Chinese phenomena is like 2nd industrialization in history)
4. Russia (Despite of its poor economy performance in post Soviet era, it still the 2nd most powerful military force after US (in terms of nuclear capbability).
5. India (the 4th largest economy in terms of PPP---Never been a Superpower like Rome or China in the past, but India is one of the most promised economy in the world. Just look how many NASA has Indian enginners and scientists, I heard its like more than 1/4 of NASA scientists are from India, and best of all they are so cheap in hiring).
