I never actually stated that the U.S was trying to establish ISIS in its current form. If you had bothered to read the article, you would have known exactly my thinking.

a recently declassified secret US intelligence report, written in August 2012, which uncannily predicts – and effectively welcomes – the prospect of a “Salafist principality” in eastern Syria and an al-Qaida-controlled Islamic state in Syria and Iraq.
