You wont get those things, not because its illegal but becuase its impractical. You dont have enough money to convince Lockheed Martin to back out of its exclusive contract with the U.S. military so it can sell you an F-35. The only people with nuclear weapons tech, or M1A1 Abrams tanks, is the US military, and the not selling that.
Like I said, it seems like a flat out stupid idea. Until you look at Syria. Or Iraq, for that matter, where the formation of neighborhood militias with sizable weapons caches (not tanks or planes, but assault weapons) has actually stemmed violence there and limited abuse of the Shia-led government over its once-unarmed Sunni populace.
Anyhow, my personal view is that the Constitution was written for 18th century America. A modern America needs a modern Constitution, and this is seen by considering the original intent of the 2nd amendment. The amendment should be repealed, but until it is, we are stuck with it.
