No, it wasn’t. It was founded on an impotent central government. It later adopted checks and balances when it decided it needed a much more powerful central government and what it was founded on was unsuitable.

But just because US Gov 2.x lasted longer than 1.x doesn’t mean everything in the 2.0. release was perfect; its certainly needed many minor and bugfix releases, and there’s no reason to think that it might not at some point need another ground-up rewrite.
