Food for thought:

Civilians and military experts expected in 1919-1938 that the next major European war (if there would be any) would be all about poison gas warfare. Poison gas bombing against civilians, millions of civilian deaths...and Germany was militarily impotent at that time, till about 1937 at the very least.

(Almost) no poison gas was used in WW2.



I believe that this "there will be no war between nuclear powers" is ideology.
A (kind of) war between nuclear powers on the terrain of a third nation already happened; Russian fighter pilots flew over Korea and fought against U.S. fighter pilots. The intensity of this was greater than the Kosovo Air War.

Never say never, you'll be caught unprepared if you do.

The threat of nuclear arms didn't make us save our conventional forces in the Cold War, why should that be a good idea today?

Our potential challengers are just not ready to strike us within few years, but it might happen in 5-10 years.


That's why the ability to expand military power quickly and launch that project with little lag is so important.
