As per Indian Penal Code, if a person murders someone in the fit of anger, then it is not considered as murder but classified as Culpable homicide not amounting to murder. I think same thing applies in international relations. If our forces had bombarded terror locations immediately after terror attack, every country would have supported us. We keep on planning the retaliatory action and then start seeking the support of international community in the hope that all the countries of the world would support us. In this process we lose the initiative. Let us face it that Pakistan has a benefit of its strategic location and China which is having veto power stands behind it. When Americans imposed sanctions on Iran, we refused to break the diplomatic relations with Iran saying that we have friendly relations with Iran. Same thing applies to Pakistan. We should not expect that Arab countries will take any tough action against Pakistan. 
We are a developing country and we can incur expenditure on the purchase of military equipment up to an extent. Let us face it that even if we purchase 100 Rafaels, we won’t be able to face the collective might of China and Pakistan. Our divided polity and society won’t permit us. We are still having 3rd generation MIGs in our fleet when even Pakistan is developing 6th generation fighter planes with the help of China. So what is the option.
We will have to come out of Nehruvian philosophy of Non alignment. Let us make our priorities clear. Whether we want to make a great Asian alliance of Russia, China and India to combat America or we want to ally with America to contain China. We enter into strategic relationship with America, conduct joint exercises with China and purchase defense equipments from Russia in the hope all the three countries would support us. It is not possible. Trusted friends are only a few. Others give you only lip service and sympathies. If our friendly country has not that much trust in us that we won’t hand over the technology shared with us to their enemy nation, it won’t give us technology and send its forces in the hour of crisis. 
We had developed nuclear weapons as a deterrent. But we lost that initiative by declaring that we won’t use it first on any country. Means we will nuke Pakistan after Pakistan has destroyed our major cities and killed lakhs of our citizens. What is the use of this deterrent. Will international community permit us at that stage to make a counter attack. I think we must revisit our strategies
