The Persian Gulf, in the Southwest Asian region, is an extension of the Indian Ocean located between Iran and the Arabian Peninsula.
The Persian Gulf was the focus of the Iraq-Iran War that lasted from 1980 to 1988, with each side attacking the other's oil tankers. In 1991, the Persian Gulf again was the background for what was called the Persian Gulf War or the "Gulf War" when Iraq invaded Kuwait and was subsequently pushed back, despite the fact that this conflict was primarily a land conflict.
The natural environment of the Persian Gulf is very rich with good fishing grounds, extensive coral reefs, and abundant pearl oysters, but its ecology has become increasingly under pressure from the heavy industrialisation and in particular the repeated major petroleum spillages associated with recent wars fought in the region.

Since the 1960s with the rise of Arab nationalism (Pan-Arabism), starting with Gamal Abdel Nasser's Arab Republic of Egypt, some Arab countries, including the ones bordering the Persian Gulf, have adopted the term "Arabian Gulf" (in Arabic: الخلیج العربي al-khalīj al-ʿarabī) to refer to the waterway. This is controversial and not commonly used outside of the Arab world, nor is it recognized by the United Nations7 and other international organizations. The United Nations on many occasions has requested that only "Persian Gulf" be used as the official and standard geographical designation for the body of water. "Arabian Gulf" is also an ancient name for the Red Sea. Hecataeus (472 to 509 B.C.) can be stated where Persian Gulf and Arabian Gulf (Red Sea) have been clearly shown. Also a map has remained from Herodotus, the great Greek historian (425-484 B.C.) which introduces Red Sea as the Arabian Gulf. 
We Iranians do care about our country and names relating to it, specially when those names are recognised by UN and other world organizations for many many years, and if suddenly lets say somebody by the name of Nasser of Egypt or Saddam of Iraq or sheik Mohamad of Dubai, just for the sake of their own political achievements start calling the Persian Gulf something else, what does this indicate? is this an Israeli conspiracy? I dont think so !
The name is just a name, but if some influential people start menddling with it, then it will get sensitive, so my advice is that just leave the historical names alone ! the Persian Gulf will be just that for many more years to come, no matter what.
What's in the name!, if you don't agree on those names than name it blink. The main problem is that we associate things according to our egos and this create disharmony all around us. This is just a futile debate that we are more superior and you are less. This is a game to divide and rule some specific geographical locality. Haven't we learned something from the history?!!! and than we say history repeat itself….because like insane person we repeat the same mistake again and again and expect different results.
