Advantages of Confederal System The system brings small and weak sovereign states together to become powerful one.
Confederation makes the governance of areas with diverse governments possible and also helps the state concerned to influence international politics.
Confederation provides room for each group in the states to maintain, retain and practice its own culture without interference from other groups.
The legal right to secede, pull or break away by any disenchanted individual state is seen as a positive instrument which tends to prevent issues of marginalization, domination and discrimination from arising in a confederal state.
The system promotes mutual cooperation of member states on certain essential but sensitive areas like trade and defence.
