You need to go over and check out this post by Donna over at Email From The Embassy. She takes on the comments about questioning diplomats' motives far better than I did (and we all have our fingers crossed for her as she submits her QEPs...because she is awesome).
Here is just a bit of it:
"People don't always agree with each other in the Foreign Service, and people don't always get along on a personal level. But Foreign Service officers always advance the agenda of our government, without fail. And they work together, no matter their personal beliefs. Because that is what they were hired to do. Imagine that, if you will: Democrats and Republicans, all working together on behalf of our nation - it happens every single day in the Foreign Service.
And here's the kicker: if he somehow manages to pull off a victory, those very same Foreign Service officers whom he just mindlessly insulted will stand up and support his policies across the globe.
Because that's what the Foreign Service is about. Diplomats support American ideals in every country across the globe, often at great risk to themselves and their families. Diplomats (and their boss, the Secretary of State) don't set their own policies. Rather, they serve as boots on the ground, the eyes and ears of the President in every corner of the globe. Diplomats report back what they see and hear and think in these countries that Rick Perry has probably never considered visiting. They present the facts - and yes, they present their own educated opinions - so that our President has the information he needs to create and direct policy. Once the President decides on policy, these same diplomats work to advance his agenda. Not their own agendas, mind you. Never their own agendas."
