I don't blame him. His family is comfortably living overseas. I blame those Afghanis who supported him. They could've chose someone who has more at stake and deeper ties to Afghanistan. He shouldn't have jumped ships abandoning his land.
Right now, there are reports that Taliban is facing difficulties in having state machinery ( banking, networks, finance, energy etc) run because they don't have anything resembling a degree or good education. This has forced them to call back those who previously used to work in the government. I sense an opportunity for everlasting settlement here.
