Wrong again.  So far you have only based your claim on a web site.  Iranica does NOT say that Aryanem Vaejo is in Afghanistan, nor does Iranica say that any part of Afghanistan has ever been called Ariana.  If it does, paste the EXACT quote here WITH A LINK to that article.  The association of Afghanistan and "Ariana" for the FIRST TIME IN HISTORY appeared after World War II and this includes the name for their airlines "Ariana Airlines".  You seem to be of the mindset that no matter what, nobody should change what you put in the articles. This is indicative of poor upbringing by your parents. Your parents have produced a foolish Mr. Know It All who is not smart enough to distinguish between the real world and the our-son-is-never-wrong environment of his mommy's house.  This is stupid.  I have offered plenty of serious and verifiable examples that shows what you are forcefully injecting in this article is wrong,  but it seems that you are only interested in a stupid and stubborn childish game of just winning an argument at any cost, no matter what the truth is. Tell me which of the following points is wrong:
1- No reputable scholar has ever claimed that Aryanem Vajo is in Afghanistan.  

2- One scholar, the late Professor Bahram Farahvashi, who dedicated his life to Iranian studies and has several respectable publications, including his award winning Dictionary of Pahlavi Language, has a book by the title of "Iran Vij" which is precisely about Aryanem Vaejo which Zereshk claims to be Afghanistan. According to this book, as well as other scholars, Aryanem Vaejo is next to the Caspian Sea.  Farahvashi also mentions the names of the scholars who think (and gives their reasons as to why they think) that Aryanem Vaejo is next to the Aral Sea.  In no case anybody has suggested it is in Afghanistan.

3- In at least three of the Achaemenids inscriptions (by Darius I and his son Xerxes) where they mention the word Arya  (that is, the Old Persian word Arya) in the SAME INSCRIPTION they also mention Haraiva (modern day Herat which was recorded as "Aria" in Greek texts) as one of the provices under their rule.  The two words are DISTINCLY DIFFERENT words with different spellings.  Only due to the Greek rendering of Haraiva as Aria this confusion exists today (and even then, it surfaces after World War II, because someone found a way to associate Afghanistan with "Aryan" and others picked it up.)

4- Unlike what Zereshk claims, Encyclopedia Iranica DOES NOT say that Afghanistan is the same as Aryanem Vaejo nor does it anywhere say that Afghanistan has EVER been called "Ariana".

5- Show me one authentic source from BEFORE WORLD WAR II, that shows any part of Afghanistan has ever been called "Ariana" or "Aryana".  Just one source would be enough, but it has to be an authentic and academically acceptable source, such a book from antiquity or the like, and NOT afghani web sites from the 21st century.  By repeating that the "official afghanis website says so" you only show how weak your argument is.

5- Last but not least, in your revert message you offered the reason [this is] "the OFFICIAL POSITION of The Islamic Republic of Afghanistan"  well, that is not good enough.  Wikipedia is an encyclopedia not the official website of Afghanistan.  What "the OFFICIAL POSITION of The Islamic Republic of Afghanistan" is irrelevant here.  We are interested in correct information.
