The recent tensions between India and Pakistan have led to many wondering whether an all-out nuclear war between the two countries is possible. While the idea of a nuclear war is certainly scary, it's important to remember that both India and Pakistan are nuclear-armed states, and thus any conflict between the two would have devastating consequences. 

There are a lot of questions that need to be answered before we can say for certain whether India can protect itself from an all-out nuclear attack from Pakistan.

The first question is, does Pakistan have the capability to launch a nuclear attack on India? 

There is no doubt that Pakistan has nuclear weapons and the capability to deliver them. Pakistan has a number of nuclear-capable ballistic missiles, including the Ghauri, Shaheen, and Hatf series. Pakistan also has a number of nuclear-capable aircraft, including the F-16 and Mirage III.

However, it is not clear that Pakistan has the ability to launch a nuclear attack on India. Pakistan would need to overcome a number of technical and logistical hurdles in order to launch a nuclear attack on India.

The second question is, even if Pakistan did have the ability to launch a nuclear attack on India, would India be able to protect itself?

That being said, it is possible for India to protect itself from a nuclear attack from Pakistan. In fact, India has a number of measures in place to ensure that its citizens would be safe in the event of a nuclear attack.

Firstly, India has a strong anti-ballistic missile system, which is designed to intercept and destroy any incoming missiles. Additionally, India also has a number of nuclear shelters which could be used to protect citizens in the event of an attack.

Furthermore, India has a policy of 'no first use' when it comes to nuclear weapons, meaning that it would only use nuclear weapons in response to a nuclear attack. This policy acts as a deterrent, as Pakistan would be aware that any nuclear attack would result in a massive retaliation from India.

Overall, while the prospect of a nuclear war between India and Pakistan is certainly alarming, it is important to remember that India has a number of measures in place to protect its citizens in the event of an attack.
