These open sources are fake news without any basis.
DRDO chief has said that Kaveri is complete but it is not having enough thrust for LCA :

This means that LCA gets 85kN from F404 but Kaveri gives less than that. According to DRDO website, it is 81kN. So, this means LCA will not be able to carry 4ton payload with Kaveri and will have to make do with 3.5+ ton.
Moreover, I don't see how these open source fake news went this far as to claim Kaveri as failure when it was clearly said that the dry core of the Kaveri will be use for Ghatak UAV. The core is the main part and if that is complete, the engine is almost done. After burner is having very limited number of parts and hence can't be complicated. Here is the news of ghatak using Kaveri core:

If Kaveri was a failure, it core can't be used for any other thing either. So, one of the 2 news is inconsistent. Since DRDO chief has confirmed Kaveri development, it is obvious that the news of junking Kaveri is fake news
Do you really think that India will allow any sea route access to Pakistan? Naval blockade will be the first step.
Indian fuel consumption is 4.3MBPD and India has 65-70 days of inventory with refiners and also has 20-25 days of strategic fuel reserves. This means close to 350 million barrels of fuel storage. Pakistan consumes 0.5 million barrels a day and has 45-50 days of storage. This means about 25 million barrel of fuel. In war, all non essential activities will be restricted and fuel will only be given to strategic activities. This means India will be able to use about 15 times more fuel to its strategic activities than Pakistan.
Nevertheless, India would prefer to have coal liquefaction and hence unlimited fuel supply before it starts any war. In case Pakistan starts a war, India will have far more available fuel than Pakistan. India will keep increasing its inventory and fuel storage over time to keep up with reserves of Pakistan
Has Pakistan detonated any thermonuclear bomb yet? India has detonated one miniature thermonuclear bomb of 45kT in 1998 (it was miniaturised to reduce earthquake impact on villagers). Pakistan did not do any such test.
Second, we are talking of fuel for planes, tanks etc which means liquid fuel like diesel, kerosene.
