I personally think this is very believable.
I know, I've been waiting for the S to HTF for years now, and I'll admit I'm surprised how long they've managed to keep things together.
But they can't keep it together forever. It's mathematically impossible.
Actually, a financial collapse is one of the "easier" things to prepare for. It's not one of those things were everyone dies or is totally screwed.
But even if only a financial collapse were imminent, it very well might lead to a big war, because you have to look at things from the perspective of the Powers-That-Be. War is a great way to distract the people, get them fired up with blind patriotism, and even reset the economic clock (clear debts, start a new currency, etc.)
Anyhow, why don't you look at this from the opposite perspective. Picture that you're a traditional Catholic that works in Washington, DC (they do exist, you know!) Say you have a friend who has connections, and he warns you but insists that you don't reveal ANYTHING that might point back to him. What would you do?
You'd go on CathInfo, and post a friendly warning anonymously, giving as much information as you can get away with -- which might not be much!
And people would react to it exactly like people have reacted to this thread.
