No, the Federal government having a standing army is what leads to us invading other countries. This is a terrible, terrible thing. It is far harder to forward deploy individuals that are only required to defend their homeland.

Also, we've seen all the institutions you mention collapse in the face of disaster. It would be far better for the citizens to be responsible for themselves in a collation with larger bodies than be dependent upon those larger organizations. For example, in Florida it makes sense to have the community trained on preparation and local response. People need to know what to materials to gather and what is already stockpiled locally. In the face of a hurricane, the community guard, i.e. the people, would be responsible for triaging the situation until reinforcements arrive. As it stands, the people huddle together en-mass hoping that the Federal government, or even the State will come to their rescue.
