^^ Every country in this world follows its strategic interests. Even if that means creating very very odd alliances.
For example, right now india is funding/arming TTP in Pakistan, even though there might not be even smallest of overlap between their ideologies. TTP is pursuing this alliance because they want money and power they have a common enemy hence a common strategic interest.
USA financed/armed/trained these very Talibans they are fighting against now because at that time it was a strategic necessity. And even today if they are sure that by making peace with Taliban will lead them to their strategic goals, they will not waste one day.
Pakistan is no different.
it is people like u who will not let pakistan get out of this quagmire... simply stating that india supports ttp wouldnt make it a fact... cmon show us ur indian version of kasab.. haha.. yeah this happens only in ur dreams.. .
usa trained the talibans along with the isi and used them at free will in kashmir.. until 9/11... when they finally bit their own masters... live with it..
