It all comes back, once again, to Pipelineistan - and one of its outstanding chimeras; the Turkmenistan/Afghanistan/Pakistan (TAP) gas pipeline, also known once as the Trans-Afghan Pipeline, which might one day become TAPI if India decides to be on board.
The US corporate media simply refuses to cover what is one of the most important stories of the early 21st century.
Washington has badly wanted TAP since the mid-1990s, when the Clinton administration was negotiating with the Taliban; the talks broke down because of transit fees, even before 9/11, when the Bush administration decided to change the rhetoric from "a carpet of gold" to "a carpet of bombs".
TAP is a classic Pipelineistan gambit; the US supporting the flow of gas from Central Asia to global markets, bypassing both Iran and Russia. If it ever gets built, it will cost over $10 billion.
It needs a totally pacified Afghanistan - still another chimera - and a Pakistani government totally implicated in Afghanistan's security, still a no-no as long as Islamabad's policy is to have Afghanistan as its "strategic depth", a vassal state, in a long-term confrontation mindset against India.
It's no surprise the Pentagon and the Pakistani Army enjoy such a close working relationship. Both Washington and Islamabad regard Pashtun nationalism as an existential threat.
