I would think that just as Stealth technology has advanced over the years,
that so to has radar technology advanced. So, where in the past radar could
get a return from something size "X" now it should be able to capture and
enhance the same return from something much smaller.

This is certainly true. Both the Horten Ho-229 and the Northrop YB-49
proved to be invisible to 1940s radar. I doubt they would be today.

Of course as greedy American corporations keep out-sourcing engineering jobs
to India and China we can soon expect those countries to start making
significant gains in military technology at our expense.

Yes, well, I suppose we could close our borders to all trade and
re-live the 1930s. Oh, but dang it! In the 1930s it was the European
countries that made all the significant gains in military technology,
wasn't it?
