We are actually more than happy to see US setting its alliance with india. This will atleast make things more clear, which wasnt in case when they claimed to be our allies. Back then they actually never wanted to be our ally instead they just had to form good relations with us because of the war on terror, but now their policy has also shifted with the end of the war, which was expected and predicted by our policy makers. We knew this day would come when US will show its back on us. We are not pretty surprised with it instead its actually good for all countries in this region.
If we look closely US is actually wants to increase its influence in world and wants to make china to play in back foot, which they will for some extend after getting alliance with India, and what india needed is a strong ally which came to them in shape of usa.
On other hand this move will be equally be proved good for China and Russia as well, since this move will bring them close to each other.
And as far as Pakistan is concerned as i said earlier we have actually gained more than anyone from this development. We both had lots of confusions regarding each other. Public from both sides were divided, some people from our side deemed them as our enemy hidden under the mask but some considered them as ally and same goes for them as well. The word "confusion" actually was the thing which never brought our relationship into the next level. So this development is actually more beneficial for us in case that we have now clear our all misconception and will know what is black and whats white.
And some people are saying that Pakistan has lost its ally and now its alone and thing like that, but always remember when there is a vacuum then obviously others will come in to fill it.
And most important thing which we didnt put it into the light is actually the dynamics of the Afghanistan. When Americans were there, india was given a sort of protocol. They were allowed to deepen their roots over there. But now things will going to change dramatically after the withdrawal of americans. And things will become more intense if NATO also leaves the region. This will make things pretty hard for indians, as they will be left behind. And after the withdrawal there will be a civil war in the Afghanistan and i m sure that taliban will set their government over there as they did decades ago. And thats also one reason why we are actually sending afghanis back to their country. Anyway we will actually witness more attacks on indians in afghanistan in future, or may be all the Afghan taliban and alqaeda will look towards india as their enemy. Who knows!
Things are indeed getting pretty nasty!. If india wants to stabilize the region then they should and must forms a good relation with Pakistan and China as well
