USA's economy was saved from a depression by WWII, so....yeah
The truth of that statement is questionable, as the Depression may have ended anyway. Significant as WWII was, it was not the only thing that happened in all the world during that time period, and there had been a lot of programs in place to kickstart the US economy. It would be naiive to assume that the war was the only acting factor. Furthermore, it is uncertain to what extent the various spoils of war contributed to the economic upturn.
More importantly, that fact that it helped one time is no indication whatsoever of a general trend. We've been at war for over 5 years now, and we went from the height of our economic power to the lowest it's been in more than 50 years.
