Somewhat. To be clearer, it is less a "the US had this brilliant idea for deep shooting", which we see hinted at in the 30s by Soviet theorists, and then talked about in the 70s and 80s again, as it is "the US managed to put together the joint communications package, appropriate staff officers, right authorities, and tied it all to correct technology to make the day to day execution of it in quick turn arounds a reality" as opposed to having a substantially longer delay limited by either technological - or organizational - issues.
