The article quoted says the Interior Ministry of Yemen called threats of Terroistist Plots targeting vital institutions and government buildings as one of the reasons they partnered with the USA on the drone strikes. Also in the northern part of Yemen the muslims are battling it out with each other for control...doesn't sound very democratic to me. I do not sanction drone strikes, but at the same time, the US isn't the only one involved here. Personally, it would be fine to me if the US pulled out of all middle eastern countries and let them kill each other in their fanatizism.
We have enough problems control our own population from killing each other, we should mind our own store first and if there is something left, give it back to the local communities and citizens.
