The Founding Fathers had the right idea at the time but the times have changed. We no longer live in a world where wars are fought muzzle to muzzle making militias feasable to defeat an invading foe. Today wars are fought in the sky by multibillion dollar jet fighter programs which would be fiscally impossible to maintain at the militia level. Militia still has its place but to oppose even a moderately powerful enemy a strong centraly controlled and financed military is needed.
The "times" nor people have changed one iota. The Constitution allowed for
a standing Navy to protect our borders from an invasion by sea (which would
be made up of foreign powers). In considering today's technology it can
easily be assumed a standing Air Force is allowed.
There has always been a standing federal Army which prior to the Civil War
was extremely small. In peacetime they collected reports from the various
State Governors about organised militia drills. During a ground invasion
they would coordinate movement of people and supplies.
We could still have a Navy, Air Force and various strategic armories around
the country. The central stranding army which is more powerful than the
states and controlled by a single man in the Capital is certainly NOT what
the Founders had in mind since history has shown that this leads to
Empires and dictators.
The Founders didn't think we should have a large standing Army, and until the Cold War we didn't have one. I think we're paying the price for our lack of vision now, as we have to fight more and more wars with a larger and larger military. It's never going to end unless we wind down the whole shebang and keep only a small regular army and a true guard force that cannot be shipped overseas.
That would be nice except that the people who make the decisions in this
country have a lot of stock options that would suffer if the US wasn't
sending soldiers overseas. Likewise, the globalists prefer to see US blood
(and UK) spilled policing the world since we are the only people who would
oppose them when the screws get the real tightening --you've seen nothing
yet. We end up with a very sick symbiotic relationship between our own
banana republic wannabes in this country and globalists overseas.
Again, this is why the Founders put a 2nd Amendment in the Constitution
since they knew freedom wouldn't be maintained by the good intentions
of law-givers-deciders in a central capital. History shows they
all
become corrupt despots.
