I dont know if the word islamism exists in english, but it exists in french, it means a radical view of islam. Doing the job is not the point here, let those people find democracy themselves, like we did, let them appreciate democracy because they will have fought for it. The US are pretending to mainly be there to install democracy, i don't believe that (i believe your fellow americans believe that, i believe they are good people, but not the leaders), but even if this was the main reason, it would not work.
