I wouldn't make that argument, because the conclusion is one that ends very poorly for Wikileaks.

I like the concept of Wikileaks, they were leaking valuable information, and seemingly handling it in a way that minimized the risk of harm to people on all sides.

If their actual mentality was aligned with your post, meaning their goal was to leak information and ignore the consequences, then I would fully support the US doing everything in their power to stop them.
