the league of nations focused on diplomacy more than the un.
the league of nations did not attempt to prevent global conflicts.
the un has less diplomatic power than the league of nations did.
the un has an enforcement arm to aid in peacekeeping.

The League of Nations lacked a strong enforcement mechanism. In contrast, the United Nations has the Security Council, which can authorize peacekeeping missions and other enforcement actions (like economic sanctions or military force in some cases) to maintain international peace and security. This enforcement - related difference is a key distinction.

The UN has an enforcement arm to aid in peacekeeping.
