China is hopelessly behind, ... recent testing of a so-called "stealth fighter" prototype indicates
Anyone subscribing to this sentence is somewhat delusional. The existence of the Chinese copy of the U.S. 'stealth' aircraft made the Americans sit up and pay attention. After a U.S. stealth aircraft was downed during the Kosovo non-war the Chinese went around buying, for cash, all the scraps of the plane from which they designed/rebuilt for their own air force.
U.S. analysts estimate the Chinese are only about 4 years behind in this project which means they will be current in a couple of years time.
They already make civilian and military aircraft and are on the way to launching a space station, unaided, which lends further credence to the fact they are sufficiently technologically advanced to match the U.S. on an equal footing.
The West has supplied much of the IP and technology to the Chinese in the rush to acquire modern products are amazingly low cost. If anyone thinks the Chinese even honour production agreements they are fools. Nothing made in China is privy to the manufacturers - all can be considered shared with the military manufacturers.
China leads the world in the use of high-speed transportation; in building railways in poor conditions, etc. They have a very healthy integrated circuit design and manufacturing industry and even though they might not be up to the latest standards used by Intel, they are not far behind.
The Chinese are currently preparing to build aircraft carriers - of which the UK has none!
The Russians have long had jet fighters that can take off in inclement conditions, including grass or mud fields. The U.S. jets require runways be 'walked' before they can be used to remove all debris, etc. before their jets can take off.
The U.S. is an unreliable source for products as it retains control of their use, in the fashion of Apple, even after delivery to it's customers. It has even flexed it's muscles when the UK used U.S. facilities to execute military missions that didn't meet American expectations.
Today's military weapons are so advanced that even shells can be 'programmed' on the fly and this includes rendering them harmless - other than for the fact a whole hunk of metal is headed your way.
Ghadaffi was dumb to buy American weapons with smart technology, he should have bought supplies from the Russians or Chinese whose less sophisticated weapons still work even when fired at the suppliers.
Even the British had to seek technological assistance from the French in order to neutralise missiles fired by the Argentinians during the Thatcher Falklands escapade.
Now that Britain is essentially stripped of it's advanced military industries it is little better than Ghadaffi being dependent upon others for it's military capability, such that it is. Hell, they even depend on U.S. designed radio systems.
