What comes next?

Looking at the current conflict makes me feel like we are approaching it in the same exact way we've approached every other conflict in the middle east.

-Kill bad guy -Install new leader and institutions -Refuse to dedicate the massive amount of resources necessary to safeguard those brand new institutions -Surprise Pikachu when an extremist group topples the fledgling institutions

This is just vibes based for me (I am closer to being a clam than a foreign intervention expert) but from my laymans perspective it really doesn't seem like we have a plan for what comes after the fighting.

Is trump going to dedicate troops and money like we did in Afghanistan? Are conservatives going to approve of another 20 year maybe baby nation building project? Is there any indication that there's more thought being put into this than "we gotta go get that guy."

I'd really appreciate if someone more knowledgeable could give me an idea on wtf we're planning to do or at least what your opinion is on what the current admin is going to do.
