No one is going to invade China, the U.S., Russia or any other nuclear power, ever. Why the Hell do you think the Iranians want a nuke so bad?
First, my point was that we stop developing capabilities and ramp down just as we did post WWI - it leave the possibility open for another power to rise up in the vacuum of brute force...
Sure we can built planes that we already have quick enough - but in the mean time other nations continue on developing capabilities and "catch up" to us as we stagnate...
Time and tech does not stand still - we are not talking about propeller driven aircraft that GM can crank out instead of Trucks inside 3 months...
Second, "no one would is going to... ever"...
The most foolish words in global strategic thinking ever uttered...
Also the most common (mistaken) words in global strategic thinking...
The thinking on what Russia would do after WWII WRT to Berlin? "They can't just build a wall? Really? They are !@#$ing building a giant wall?
Just because nukes are on the tables does not mean they are used. Just because they are not used, does not mean fighting will not occur...
The capability of those we are going to fight in the next 20 years is going to develop at a RAPID pace as a function of the internet and the promulgation of education around the world that we have facilitated...
Everything that you are saying is a variation of the same stuff that people said after WWI ( "the war to end all wars"). "No one will do this", "no one will do that", "It would be insane to do X, Y, or Z"...
All the while Germany and Japan built war machines while the US and Europe were dismantling theirs...
The F22 represents much more than just a VERY capable dog-fighter... MUCH more... Some of that lives in the JSF, but not all of it... The JSF is an exercise in design by committee... Compromise after compromise - something for everyone...
I am not suggesting that we blindly build a plane to fight the Soviet Union that no longer exists, but we are foolish and arrogant to think that we can ignore future technologically advanced threats...
