I doubt it within certain sections of the US political elite. Many of those who went all gung ho about going into Iraq in 2003 still have influence in US right wing political circles, either personally or through acolytes and supporters. Whilst the neocons are not as visible today, they haven't completely disappeared.
After Vietnam the US was quite risk adverse of foreign adventurism until the Reagan Administrator. Whether it becomes risk adverse of foreign adventurism again remains to be seen. I don't hold much hope though because it's had 40 years of it and old habits die hard.
