What was Anwar Awlaki's opinion about Hizb al-Tahrir's method for establishing the caliphate?

This is his summary of what he differed with: "Regarding the method of HT which you specifically referred to in your question, I first came in contact with HT members from Jordan in the early nineties and found them to be argumentative but well-mannered and polite. My first understanding of the Hizb was from them and they were core members of the group. HT has played an important role in raising the awareness of the ummah to the matter of khilafa. They also played a role in countering the false idea that politics and political awareness have nothing to do with Islam. However the method of HT to re-establish khilfah is simply not going to work. To wait for nusrah until it arrives is to wait for a miracle. Tribes or military generals that are supposed to give nusrah and establish the religion of Allah are not going to be won over simply by discussions. They will only be won over when they see a group of believers living by what they say and sacrifice all that they own for the sake of Allah. This is what will inspire others to join. The two success stories of powerful people giving nusrah to the religion are some of the former officers of the Iraqi baath regime who joined the insurgency and the former president of Chechnya, Dudayev, who was a high ranking officer in the Soviet army. Both these successful examples of nusra were not won over through debates, demonstrations and pamphlets but by them seeing a living example of men struggling in the path of Allah. This leads me to the forth method of re-establishing khilafa and that is through Jihad fi sabilillah. The argument that you presented against this is that the only similar situation to our situation now is that of Rasulullah establishing an Islamic state first and then fighting Jihad. You are neglecting a serious difference and that is when Rasulullah established Madina there was no Islamic land that was invaded. Isn't this a serious and major difference? Today the Muslim world is under occupation and the statements of our scholars are clear that it becomes fardh ayn on every able Muslim to fight to free the Muslim land. When something is fardh ayn it is fardh ayn. You cannot theorize or hypothesize otherwise. The ruling is clear and the implications of it are clear. So even if you do not believe Jihad to be the way to establish khilafah you must agree that Jihad is fardh ayn and that is not where HT stands. Also the jihad which is fardh ayn and is Jihad al dafa (defensive Jihad) does not require the one who wants to participate to seek the permission of the Imam, parents, husband, slave owner, or lender."(Source: Kalamullah.com)
