The evolution of diplomacy

Since the aftermath of the world war II, diplomacy has changed in a very significant way it is no longer a government to government affair it has broaden to government to international (foreign ) people connection which is commonly known as public diplomacy. When the Second World War ended, an amazing development occurred.
Diplomacy was re-established, but the government-to-people programs, previously confined to wartime, and continued. There are several theories as to why this happened. The two most often cited are that the war had speeded up
the information revolution, which now dominated practically the entire globe,
and that the world was basically divided into Western and Soviet orbits, with
both trying to extend their influence

Initially diplomacy was all about states using diplomacy to protect their own interest but now it is not solely the case because with the presence of private organizations such as the non-governmental organizations (NGOS) things have taking a new shape , Globalization during the 20th century gave rise to the importance of NGOs. Many problems could not be solved within a nation. International treaties and international organizations such as the World Trade Organization were perceived as being too centered on the interests of capitalist enterprises. In an attempt to counterbalance this trend, NGOs have developed to emphasize humanitarian issues, developmental aid and sustainable development.

Diplomacy has changed significantly and the effectiveness of (NGO’S) is one of such reasons and most importantly public diplomacy as a whole is one of the major factor that differentiate the old diplomacy from the new diplomacy.
