No matter what other people say, MB was an Indo-Soviet tool in their hybrid war agaist Pakistani state with largely Indian soldiers disguised as indigenous Bengali fighters. A decade later the same Indo-Soviet axis started working hand in hand in Afghanistan which still persists till date. 1947 partition did not allow the Indians strategic access to the Middle East and central Asia despite the huge territory they obtained. Instead, liberated sectors of Kashmir further undercut their strategic access. On the other hand, the Soviet could not finish off their 'Great Game' during the British Raj. They too were very excited to finish off their 'Great Game' by obtaining access to the much fancied warm water of the Arabian sea.
Therefore, we must solve our Afghanistan project first in order to deal with the Indians at the later stage.
