> Is there any political tool

It's a social problem. Smaller democratic political arenas work closer to the ideal. Larger political arenas have more noise and less concise agendas, because of the disparate groups being appealed to. The US is too big. Large societies, across time trend toward authoritarianism (sometimes leading to full-fledged) until revolution and dissolution. Then the remaining states fight amongst themselves within a region, assembling into a singular organization due to practical and political factors, until it starts over again. Eventually you get something like europe and most of southeast asia. States tend to be more stable if they roughly match their regional terrain boundaries and aren't too large.
