When a country can't repay its debts, negotiations with lenders happen case by case with no consistent rules, often favoring lenders over the country's ability to recover. This can trap nations in cycles of debt renegotiation that stall development for years.

A country can be found in violation of international law and simply ignore the ruling with little real consequence, especially if it holds significant economic or military power. This selectively weakens the rule of law based on who is being judged.

Voting power at bodies like the IMF still roughly reflects the economic order from decades ago, giving less voice to countries that now represent a huge share of the world's population. This mismatch fuels distrust in the fairness of global rule-making.
