Step 1: Managing interdependence:
In an interconnected world, no single country can address issues like terrorism, climate change, trade, or health crises alone; international organisations provide a platform for collective action.
Step 2: Preventing conflict:
Bodies like the United Nations offer forums for peaceful dispute resolution and mechanisms (like peacekeeping) to prevent wars from escalating.
Step 3: Setting common rules:
Organisations such as the WTO and WHO create shared rules and standards — for trade or health — making international interaction predictable and fair for all members.
Step 4: Providing aid and cooperation:
They channel humanitarian and developmental assistance to poorer nations and coordinate joint responses to global challenges, something that bilateral diplomacy alone struggles to achieve efficiently.
