And those procedures are THE STATE AND LOCAL GOVERNMENT TAKES THE LEAD AND THE FED PROVIDES THE ASSISTANCE THEY ASK FOR.
If the state and local governments completely fail to do their jobs then the federal government has to invent, on the spot, a replacement to take over. That takes a few days. Oh, and the only way the President can exercise that option, under law, is to declare the state "in insurrection." Of course, that would mean he would have to move in troops to first shoot those in state and local government. Then they could look to providing aid and comfort to the citizens.
What part of the civics 101 concept of federalism don't you understand?
"Of course, that would mean he would have to move in troops to first shoot those in state and local government."
Sounds good to me!
