Why Does Iran and Afghanistan HATE Each Other?

You would think that the Islamic terrorist organization of the Talibans would be a great friend of the Islamic Republic of Iran, but you would be mistaken.
What if I were to tell you that in actuality they might draw close to a war?

Today we are going to answer the question:
Why Iran and Afghanistan don’t like each other?

The border between Iran and Afghanistan spans over 900 kilometers, a border that is full of tension over water.

Afghanistan has a number of rivers, the most important of which is the Helmand River.
The Helmand River terminates in the Hamun Lakes, a place that has great importance in Iran not just for agriculture but also for drinking water. And because 95% percent of Helmand is under the control of Afghanistan that is making Iran nervous about the situation.

The Taliban can restrict water as they please and can use this water as leverage against Iran, which is facing a ‘Water Bankruptcy’.

It is also to be noted that the level of water itself has decreased, and with a blend of climate change, declining rainfall and impaired environment, the water crisis is depriving thousands of people from drinking water.

Iran has around 4.5 millions Afghans of varying status in the country, of which 750,000 are refugees, 500,000 are undocumented, and only 360.000 have a resident permit.
Such a huge number of immigrants is bound to cause instability, plus the shared Sunny Afgan identity and they represent an economic and social problem for the government of Teheran.

In the Islamic Faith, The rivalry between Shia and Sunny is well known.
Based on theological differences, the bloodshed spilled between those 2 groups is enormous and to this day the effects exist.
Today Shia based Republic of Iran is in a mini cold war with the Sunny based Kindom of Saudi Arabia.

Afghanistan is a Sunny Muslim dominated country with a small minority of Shia Muslims. Iran is worried about the treatment of the Shia minority and if the opportunity arises would use this minority as leverage against the Taliban, in whatever situation.

Given the recent eruption of violence where people have died, it would be naive to think that the future is all flowers and no blood.
For the reasons listed before it is reasonable to believe that the situation will at least remain the same if not worse.
I think it’s likely that a war or a limited military action will happen.
