Yeah, Declaration of Independence, Louisiana Purchase, sending Marines against Muslim pirates, mere trifles. /s
I didn’t say he did nothing to deserve the title of Founding Father.
Often he was way too much the political theoretician, he did come up for reality at the right times as you pointed out. However even those examples are somewhat tainted. For example he almost abolished the US Navy. He thought coastal gunboats were all we needed. Someone at the last moment convinced him to keep those six super-advanced (for their time 6 (I think?)) frigates e.g, USS Constitution, USS United States, etc. For the Lousiana Territory purchase he also expected to be impeached and removed from office. He didn’t think he had the Constitutional power to do it. He used a Hamiltonian Constitutional interpretation to do it - meaning FedGov has the power to do something like that unless expressly forbidden by the Constitution. For that many of his Democrat-Republican colleagues called him a hypocrite as did his Federalist political foes.
You should read about his actions as Washington’s SOS. Using Phillip Freneau as his cat’s-paw he was undermining Washington! He & Freneau were constantly claiming through Freneau’s newspaper - the National Gazette that Washington wanted to be King. Really? How can anyone rational believe that? Even back then! Look at his actions concerning Citizen Genet! Also he was a complete flop (particularly when compared to say Patrick Henry) as Revolutionary War wartime governor of Virginia, some say to the point of cowardice.
He had flaws now completely glossed over in order to diminish the idea we are a republic and amplify the false notion we are something akin to absolute democracy. (Look what pure democracy did to Athens! The FFs knew their classical history!)
In my study of the Founding Fathers one thing I noticed, many (Certainly not all!) of the really significant FFs (At least the ones popularly quoted now!) who came from the colonial elites were very pro-democracy, however those from the “hoi polloi (and lower!)” were much more suspicious of pure democracy. In fact they were always using Rhode Island as the example, the mess pure democracy makes!
