Salaam (peace), Muslim (submitted one) both come from the verb "slm" which means to submit. I've been directly involved in the Muslim world for 20 years now, and have interacted with their religious leadership at all levels. The American Muslim Association in 2000 published its national strategy for the eventual Islamicization of the US in 100 years. A slow submission of the people and culture to Islam will produce a type of "peace." The 6th pillar of Islam, according to the Ummah and the Hadith, is Jihad which means a war against the unholy - not people per se, but it can mean infidels. Jihad is a war against all that is not Muslim - submitted to God. Opposing culture, countries, movies, dress, food ... its up there with Prayer, Fasting, and Giving to the Poor. This is the war that has been directed against us, and we cannot opt to sit it out. Islam has no restrictions on the treatment of non-Muslim combatants, and they do not define combatant by a uniform.
The Muslim world loves our new president, and see him from a religious perspective. Prosecuting the previous administration for "war crimes" would give them hope that the Madrasa training of Barak Hussein Obama as a child was effective. They may interpret that as a sign that they have succeeded in placing an ally in the top leadership role in the US, and may give them a rallying cry for recruiting and morale which has been poor in their camp for some time. I don't think he's a "manchurian candidate" for them but his administration is an answer to their prayer.
