Re: Dilemma is that a stable Afghanistan spells trouble for Pakistan
That is never going to happen not even in a million years, US will fight Russia via proxy by supporting various terrorist groups. There are two countries that US dare not take a panga with, I am sure US knows exactly who they are and knows its own limitations.
After getting a kick in the nuts in Crimea and Syria I suspect there will be a surge of terrorism in Russia, Putin better be prepared.
