But, according to the 2004 book Afghanistan: The Mirage of Peace by Chris Johnson and Jolyon Leslie, when the Pentagon began to bomb Afghanistan under the Republican Bush-Cheney-Rumsfeld-Wolfowitz-Powell-Condoleezza Rice Administation in October 2001, "there was no explicit agreement under international law for the USA to go to war."
The same book also recalled:
"The US air attack on Afghanistan began on 7 October 2001, with an initial focus on targets in the major cities...Some 400 civilians were killed in the first week of bombing, and this toll increased tenfold over the following three months of the campaign...
"By the end of October 2001...there was a switch in strategy to carpet-bombing of frontlines...Sub-atomic bombs were dropped on Taliban frontlines in the Shamali plains north of Kabul...In addition, a quarter of a million deadly bomblets were scattered from the cluster bombs that the USA dropped throughout the country...
"...Afghanistan potentially offered advantages over all the alternative pipeline routes..."
Ironically, when President Obama was an undergraduate student at Columbia College in the early 1980s, he apparently was a student of a Columbia University professor named Zbigniew Brzezinski--who later became one of his foreign policy advisers when President Obama was campaigning for his White House job in 2008.
Coincidentally, former Columbia University Professor and former Carter White House National Security Adviser Brzezinski confessed in an interview that appeared in the January 15, 1998 issue of the French newspaper Le Nouvel Observateur:
"According to the official version of history, CIA aid to the mujaheddin began...after the Soviet army invaded Afghanistan...But the reality, secretly guarded until now, is completely otherwise: Indeed, it was July 3, 1979 that President Carter signed the first directive for secret aid to the opponents of the pro-Soviet regime in Kabul."
