DHS was founded in 2003, as was ICE. The country got along for 227 years without these organizations, they aren't some bedrock thing from time immemorial.

Recognizing that the current structure and mode of operation of these organizations is problematic and leading to bad outcomes also doesn't mean flipping to fully open borders with zero law enforcement as some imply every time this is brought up.

DHS is brand new, has caused horror and terror, and soaked up tons of funding that could go to literally anything else.

It doesn't need to exist. Keep the customs checks, keep the border crossing folks. Keep port inspections. Run ourselves like a normal country and like we did for hundreds of years.

Shit is just reactionary nonsense after 9-11.

Re 2: There’s so many gov agencies with overlapping responsibilities that I’m actually surprised you ask this. You can totally close a number of them and still have a functioning government on paper. Reality might turn out different.

As per your second question, I have no answer. Dems are so dysfunctional it’s beyond parody.

You don't seem to be grasping the severity of the situation if all you care about is "what do you want as a replacement?"
