There is no doubt in my mind that our armed forces can defeat anyone else out there if there was a conventional war.
What would impress me far more than having twelve different plans to defeat the British and any combination of their colonies (yes, I am sure we still have them today) would be a plan to effectively defeat modern threats like terrorists and insurgencies. One that actually works, unlike our counterinsurgency strategy from ten years or so ago that was so complicated that only an academic could think it would work.
Defeating terrorists would involve an honest threat assessment and disruption of their recruiting & financial networks. All of that was begun after 9/11, but quickly overturned.
