What is ISI?

ISI (full form: Inter-Services Intelligence) operates to work with the sensitive information that is related to national security, all over the world. This one agency gathers, processes, and analyses information and deals with things that threaten the security of any place nationally.

ISI Pakistan

When we bring our focus to ISI in Pakistan, it comprises of the military officers who have been drawn from the three branches of armed forces who are still in service. ISI is one of the most powerful and the most influential intelligence agencies that work within the country, on a global level.

In 1948, ISI was formed, and in these years the agency has been seen working on the most vital cases, making investigations in such a way that it has made everyone consider it to be the best agency in the country.

What does ISI mean?

ISI is a world-renowned agency that is comprised of the top officers of all the three armed force, which are the army, navy, and air force. This stands true most of the time but sometimes ISI recruits people who have not been a part of any of these forces. The people working for ISI are from all over the country with different backgrounds, knowing different things. This is what Inter-Services means. It is named so because of the inclusivity of everyone and anyone with all backgrounds.

Global Recognition of ISI

ISI got globally recognized when it supported the Afghan Refugees while going against Russia, then known as the Soviet Union, in the 1980s. during this period, ISI worked with close coordination with United States Central Intelligence, also known as CIA, and United Kingdom’s Secret Intelligence Service, which can also be referred to as ISI.

What is the purpose of ISI?

The role of the Inter-Service Intelligence is to provide the government with information regarding all the things that can threaten the national security of the country. Doing this, the intelligence agency, ISI, is able to provide the first line of defense for the country and alert the respective authorities so they can man up the boundaries and provide protection with anything that they need it against.

Why do we need ISI?

An effective intelligence service, in this case, ISI, provides the authorities to prevent incidents which would be harmful to the country and protect the integrity of the country in addition to providing protection for the country and the people that reside within, regardless of their nationalities, at the expense of their own adversaries.

Advantage of ISI

Having knowledge of everything that can possibly be going on regarding the country, in terms of its security and protection, the practices of the intelligence services provide us with an advantage by having the prior knowledge which helps the concerned authorities and officials in predicting the plan of those who intend to harm the country in any possible way. This also allows the officials to defeat the opponent before they can even formulate a plan to try and act upon their threatening plans.

Major things ISI works on

  • Collects information which is critical to the country’s interest or the information which can prove to be crucial for the protection of the country.
  • Classify the information collected secretively, making sure all the required information reaches the concerned authorities.
  • Comes up with plans to decide who will work against what and collect the enemy’s intelligence information.

According to the country, the intelligence service is working for, the major operations may vary but the workings it has, in general, are mentioned above.

How is ISI received by the public?

It has been commented by a few critics that the intelligence service ISI is known to become a state within a state and it is improbable to hold it accountable for everything that it does and also the things that it does not do. It has also been observed that this might be because the work they do is bound to be secretive as they actually have spies or people who secretly work for them.

However, it has been argued that even if the intelligence services are known to keep their work and the information that they have secret but they should at least be answerable to the head of the state, whoever it may be.


Over the past few years, it has been observed that intelligence agencies, including ISI, has been accused of the terrorist groups against their neighbors, using domestic politics and controlling it however they may please and get by with however they work. In addition to this, it is also being said that because of the work that the terrorist agencies do for ISI, ISI also continues to provide assistance for those terrorist agencies.

Another thing that comes to mind when one talks about the controversies regarding the intelligence agencies is that for an organization that works in secret and does not disclose any kind of information regarding how it is operating and also keeps the information that they gather a secret, it is not possible to say for sure if the agency is actually working with terrorist groups, providing them assistance and getting services back in return. Since there is a lot of secrecy going on, the only thing that one can so believe the information that they actually get from the agency itself and not from those who are merely guessing what is going on with these organizations.

So, instead of getting fixated with wanting to devalue an organization, particularly the one whose sole purpose is to protect the country, we should believe the things that they actually tell us they do instead of making our own baseless assumptions as to what they might be doing particularly because they choose not to release all the information that they have about everything. They release the information to those who need it and while it is being acted upon, it is not for the public to know, since that is the purpose of intelligence.
