The US elections once again ring the bell: democracy can decide on method, not values.

Republicans and Democrats are equally corrupt, incompetent, and populist. Their programs are equally murky. No wonder US voters split between the Republican and Democrat electorate randomly, approximately half in each camp. In a democracy, when major forces are more or less equal, minor swing groups become decisive. Religious parties in Israel and swing districts in the US hold disproportional power over the countries’ policies.

The US, accordingly, fluctuates between pro-business and welfare policies, militancy and pacifism, moral conservatism and permissive nihilism. No policy is implemented, no end achieved, no constituency satisfied.

The ancient Greek democracies never debated such basic issues. All agreed on values: family, plunder, and trade are good. The democratic process determined how to reach those goals.

Their enemies need not fight the US but only wait for the democratic reversal. A war that drags four or eight years changes the US public mood, unseats the ruling party, and ends up with an American retreat.

Democracies should require a supermajority vote to change an existing policy.
