Some Game of Thrones/ A Song of Ice and Fire real talk for you:

I’ve come to the conclusion that Littlefinger is the hypothetical, what would happen if one of those “friend-zoned” fedora guys were a puppetmaster evil genius.

But it’s okay, because in real life none of those men are in any way capable of setting various Houses and Kingdoms at war with one another using merely the power of their words and also poison.

So the realm is safe.
