One would hope they'd learned from Iraq and Afghanistan why military invasions aren't the strategically optimal way to deal with these problems. Although that may be a forlorn hope.
As much of a clusterfuck both of those wars were, I don't think they can be shown to have been clearly bad for the US long term interests. It's a hard thing to calculate, and the war hawks would be more than willing to only show the data saying more war is a good strategic idea.
