Is the Secret Space Program a worldwide recruitment effort, and which nations are partnering militarily with extraterrestrials at the present time?

The recruitment effort is indeed worldwide and that is because this is a worldwide mercenary army project. Because if needed, the mercenary force will have to act globally and there may be tactical advantages in having troops who have no compunction about killing humans in any particular area of the planet, and their experience shows them it is easiest when bringing in humans from a different culture who feel no closeness with people from other areas of the world, particularly when there has been friction historically and this is part of their knowledge base. We, as you predicted, do not wish to divulge military secrets as this carries with it risk to you. So it is best to not answer that portion of your question.
