The difficulties involved in implementing the suggested reforms to reconstruct the UN are-

• There was no specification regarding how big an economy can become a part of the UN Security Council.

• There was also no specification regarding the required military strength of a nation for membership.

• No target regarding the required budget contribution.

• There was a clash between basis of determination of UNSC membership i.e. between geography and economic development.

• Population couldn’t be classified as an asset or a liability.

• The basis of cultural representation was also unresolved. How could one divide the world by culture and civilisation when nations contain several cultures within their borders?

• There was also a proposal regarding change in membership of the UNSC altogether. Some wanted the veto power of the UNSC members to be abolished. Others considered it to be in conflict with the concept of democracy and sovereignty of states.

The above criteria are the ones that were adopted but weren’t publically accepted and are the difficulties involved in implementing reforms to the UN.
